London & South Western Railway
DC electric suburban services

In summation the mainstay for DC electric suburban services was provided by the 3 Car Motor Units. Initially this was for the LSWR 1915 electrification (London & South Western Railway) then subsequently the Southern Electric (following the formation of the Southern Railway from 1^st January 1923) right through to these units’ Wartime augmentation to 4-car.

Usually referred to as ‘3s’ in internal railway publications, these electric units often operated in pairs with 2-coach Trailer Sets (coupled in between) to form an 8-car train.

During the Second World War these 3 Car Motor Units were augmented to 4-cars so as to bring the trailer-unit operations to a close. Eventually these augmented 4-car units were referred to as 4 SUB when the ‘Bulleid’ 4 SUB units started to appear from 1941.

Increasing Capacity

Due to the rapid growth in traffic following the LSWR electrification scheme in 1915 /1916 it became necessary to increase capacity on a number of trains to cope with demand. There were insufficient electric 3 Car Motor Units available to make-up trains to three‑unit formations and 9-car trains were too long for a number of platforms.

Two‑coach Trailer Sets

So, in May 1919 it was decided to form ten two‑coach Trailer Sets by converting five four-coach bogie block trains which would be marshalled between two 3 Car Motor Units on busy trains giving an 8-car train. The performance of the 3 Car Motor Units was sufficient to allow these 8-car trains to maintain the electric schedules.

Conversion of Steam-hauled Stock

Conversion proceeded quite slowly, with ten Trailer Sets being ready by May 1920, but in view of still rising traffic a further four bogie block trains were then authorised for conversion to bring the total of Trailer Sets up to eighteen, and a further three were taken for conversion in October 1922 bringing the total of new Trailer Sets up to twenty four.

Twelve of the steam bogie-block trains were therefore modified at Eastleigh to form the Trailer Sets, these vehicles thereby having the same body styles as the 3 Car Motor Units after conversion.

The vehicles had been built at Eastleigh between March 1904 and September 1912 and were mounted on wooden underframes with steel channel solebars. The 7-compartment Brake Thirds became 9-compartment vehicles with two new compartments replacing the former van area, these new compartments being 5' 8" wide whilst the original seven were 5' 6" wide. They now weighed 22 tons 18cwt.

Once again vehicle lengths differed, twelve of the vehicles were 49' over bodywork (51' 7" over buffers) whilst the remainder were 51' long (53' 7" over buffers). The Trailer Sets were formed with an 8‑compartment coach (eighty seats) coupled to a 9‑compartment one (ninety seats), alternate sets being formed with a shorter underframe vehicle, sets therefore being either 105' or 107' long. Overall width was 8' 10½" and they weighed 45 tons 12cwt (107' ones) or 45 tons 8cwt (105' ones) and seated one hundred & seventy third-class.

The Composites had all eight compartments downgraded to third-class, the 49' former Tri‑Composites having three compartments 6' 6" wide, three 5' 10" wide and two 5' 6" wide, whilst the 51' Tri‑Composites had four at 6' 6" and four at 6' 0" wide, though one vehicle was taken from a different batch of 51' Bi‑Composites having five 6' 6" and three 5' 10" compartments. The 49' coaches now weighed 22 tons 14cwt whilst the 51' coaches were 22 tons 18cwt.

Braking Systems

Modifications consisted of altering the braking from vacuum to the quick‑acting air system of the 3 Car Motor Units and converting the heating and lighting to work with power supplied from the 3 Car Motor Units via the jumper connections.

Power Supply

Batteries where fitted were removed as these were no longer required. No shoegear was fitted to these Trailer Sets, nor were any driving cabs provided, the outermost vehicle ends were fitted with waist height jumper connections for heating, lighting and through-control purposes, the air braking connections remaining at low level adjacent to the screw coupling. Cables connecting the power jumpers of the 3 Car Motor Units were run along the coach roofs rather than underfloor as on the 3 Car Motor Units.

Passenger Accommodation

All accommodation was now third-class, though due to the origins of the vehicles, the former first and second class compartments were wider than the original third class ones.

Couplings

Coaches were close‑coupled with the LSWR type block‑train steel disc and drawbar coupling, later replaced by the SR style centre buffer and three link chain, and the former van space end of the 9‑compartment coach was outermost, with the wider former first‑class compartments of the 8‑compartment coaches also being outermost.

Former Composites also had conventional buffing gear fitted at what became the outer end of the Trailer Set. All coaches retained their original LSWR fixed bolster bogies on conversion.

Depots

They were initially maintained with the 3 Car Motor Units at Durnsford Road and Strawberry Hill.

Smoking

The 8‑compartment coaches contained two non-smoking compartments, these being the third one in from each end of the coach, whilst the 9 compartment coach had three, located as the second from each end and the centremost one.

Into Service

The first Trailer Sets were ready for use from the summer of 1920 and were allocated set numbers T1-T24 by the LSWR, but became Trailer Sets 1001-1024 following formation of the Southern Railway in 1923. However, the vehicles were not renumbered until they required repainting; this started in 1926 with the last being done as late as August 1931.

The LSWR numbered the 9‑compartment coaches 7401 /7404 /7405 /7408 /7409 /7412 /7413 /7416 /7417 /7420 /7421 /7423 then odd numbers up to 7447. The 51' long 8‑compartment vehicles were numbered 7402 /7406 /7410 /7414 /7418 /7424 /7428 /7430 /7436 /7438 /7440 /7446 whilst the 49' vehicles became 7403 /7407 /7411 /7415 /7419 /7422 /7426 /7432 /7434 /7442 /7444 /7448.

The rather haphazard way the sets were numbered stems partly from the fact that they were delivered in three batches, the first ten in 1920, a further batch of eight followed late in 1921 and the final six not delivered until early 1923, and the numbering of different vehicle types in one number range. The SR renumbered all the coaches into a new series between 8901 and 8948 and rearranged them into individual types within this series. The new numbers were then:

9‑compartment coaches 8925-8948.

51' 8‑compartment coaches 8913-8924.

49' 8‑compartment coaches 8901-8912.

The 9‑compartment trailers were allocated diagram number 722 whilst the 8‑compartment trailers (49' bodies) became diagram number 720 and those with (51' bodies) became diagram number 721.

Livery

Coaches were renumbered as they became due for a general overhaul and were repainted into SR dark green at this time.

Bogie Modifications

The ex. LSWR fixed bolster bogies did not ride that well and accordingly were rebuilt with moving bolsters, this work being authorised by H.O. 391 dated 8^th November 1928, which also included the trailer bogies of the ex. LSWR 3 Car Motor Units nos.1201-1284. This work was completed by August 1933.

However, these bogies continued to give trouble as they wore out, and a further order, H.O. 809 dated 23^rd March 1934 authorised the provision of one-hundred new ‘standard’ bogies to re‑equip this whole batch of Trailer Sets and provide a few spares.

Lighting Jumpers

These Trailer Sets did not originally have the central lighting jumper found on other suburban stock batches as they ran with the ex. LSWR and Guildford /Dorking units which were also not so fitted when new. They were modified from about 1934 when the ex. LSWR units were rebuilt on longer underframes and made more standard with all the other units, the Western Section units then becoming common-user with the remainder of the suburban fleet from 1938.

Planned Rebuilding

It was planned to rebuild these Trailer Sets in a similar manner to the ex. LSWR 3 Car Motor Units, and Eastleigh were given H.O. 1007 dated 17-Dec-37 for rebuilding of one set onto standard underframes. However, this was cancelled from 20-Jul-38 and none were rebuilt.

Wartime & Reformations

Two sets were withdrawn following accident damage, two others were damaged during the war and not repaired and one was used for wartime purposes with the bodies grounded following accident damage, the remainder surviving in traffic until all were withdrawn between 1946 and 1949 and scrapped, the bodies at Lancing and underframes mostly in the London area, during the large scale reorganisation of the suburban fleet into 4-car motor units. A handful of this batch lasted until the end of Trailer Set operation on the SR on 26^th September 1948.

The original formations of the LSWR sets is shewn below, followed by the new SR set number and the date the set was renumbered along with the works where this was carried out. Dates sets entered traffic are shewn below the set number in the second table.

Note on Disposals

Coaches shewn as disposed of by ‘London Bridge’ are believed to have been allocated to London Bridge C&W staff for breaking, the actual location of breaking-up being uncertain, though in the London Bridge C&W area (possibly at Ewer Street or Rotherhithe Road), as coach breaking is unlikely to have taken place at London Bridge itself.

Southern Railway Trailer Set Vehicles

The origin of vehicles converted for use in the subsequent batches of Trailer Sets ordered by the Southern Railway was complex. and is shewn in detail in the sections on individual batches of sets. The following table summarises all the vehicles utilised:

Column
1	Coach numbers.
2	The sets to which they were allocated.
3	Coupling arrangement within set (C for close coupled with three link chain and centre buffer followed by CB for centre buffer fitted or RP for rubbing plate fitted, L for loose with side buffers and screw coupling).
4	The location where the conversion to electric operation was carried out.
5	Details of the underframe type (STD is new 62' 0" frame constructed at Lancing works, non-standard lengths are detailed and AC is a former LBSCR underframe used earlier in AC units).
6	Pre-grouping company which built the bodies.
7	Date of conversion.
8	Layout of the vehicle (number of compartments).
9	SR diagram number allocated to the modified body.
10	H.O. order number for the batch of sets.

All vehicles were classified as Trailer Thirds (TT). In some cases, vehicles were not allocated to sets in numerical order or a particular type of vehicle did not appear in each set, in these cases the number range of the set numbers is shewn in brackets. Similarly, some batches of coaches though numbered in one series utilised bodies from different sources in otherwise identical coaches and had different diagram numbers as a result, these are also shewn in square brackets.

The diagram numbers of many vehicles were later amended during the wholesale reforming of sets between 1934 and 1938 when many were altered to be close‑coupled to a newly converted ex. LSWR 10 or 11-compartment coach, or when they were reformed into newly augmented 4 SUB units from 1943 onwards.

Origin of Trailer Set Vehicles
(where known)

Ex. LSWR Coaches

The original identity of conversions of former LSWR stock into 10 & 11-compartment trailer thirds at Eastleigh from 1934 onwards is known, with two distinct types being used, split between those converted into 11-compartment vehicles and those used as the basis of 10-compartment vehicles.

Coaches for conversion into 11-compartment Trailer Thirds for Trailer Sets were drawn from the large number of 51' 0" 7-compartment Brake Thirds built at Eastleigh between 1902 and 1912 as the end vehicles of bogie-block suburban sets. These coaches were constructed on wooden underframes, though with some steel strengthening, though those constructed after about 1905 had steel solebars. All had electric lighting from new. They had conventional buffers at the brakevan end and the LSWR pattern steel disc and drawbar block coupling at the passenger end.

Conversion work took place at Ashford works where the body was mounted onto a new standard 62' 0" underframe (from Lancing) and the former brakevan area was removed and replaced by four new 5' 6½" wide compartments. The original seven passenger compartments were 5' 6" wide however. The resulting 11-compartment coaches were therefore now 62' 0" long over bodies (64' 2¾" over buffers) and they now seated 110 third.

One each of the vehicles were used during 1928/9 (along with an SECR conversion) to form sets 1121-1167 whilst a few more were converted in 1930/1 for sets 1188-1194. All these vehicles had new underframes with a rubbing plate fitted at what became the inner end of the set. A number of the original discarded composite construction underframes were later re-used under passenger vans.

The following table lists these vehicles in their final electric stock number series, with their original numbers and construction dates, their second LSWR number where applicable, their new SR number (those in italics were never applied), the date the vehicle was withdrawn for conversion, the new electric stock number and the initial set allocation of the vehicle.

Coaches for conversion into 10-compartment Trailer Thirds for Trailer Sets were drawn from a large batch of 8-compartment Thirds built at Eastleigh between 1894 and 1902, along with a few from a batch of 8‑compartment Second /Third composites (some of these having originally had four second and four third compartments) with the seconds at one end, whilst others had the four seconds in the centre of the coach with two thirds at each end.

The four vehicles of this type converted for use in Trailer Sets were all of the first type. These Composites were to an identical layout to the full thirds, the only difference being that the seating had side and a centre armrests dividing it into four seats across, and had been subsequently downgraded to all-third between 1918 and 1920 with the seating altered to five aside by removal of these armrests.

Virtually all of these coaches were delivered fitted with gas lighting which they retained until conversion to electric trailers, but some of the later built ones had electric lighting from new, whilst all were fitted with steam heating between 1908 and 1913. They were mounted on wooden underframes with steel flitch plates along the solebars.

Most had been renumbered by the LSWR (some of those delivered as composites more than once, all being downgraded to Thirds between 1918 and 1920), and all were renumbered again by the SR, though the process of renumbering was slow as vehicles were only done during major body overhauls involving complete repainting. The SR diagram number for these vehicles in loco-hauled format was 12.

During conversion at Eastleigh, most retained their original external appearance with side panelling with wooden overbeading. However, the last two batches converted were repanelled with flush steel panelling giving a much smoother external appearance. Two new matching compartments were added during conversion to bring them up to 62' 0" long, now with ten compartments and seating one hundred third-class.

Some of the new underframes were fitted with a rubbing plate (diagram no.731) whilst others had the centre-buffer (diagram no.732) at the inner end of the set. TT 9298 was slightly non-standard as the body was mounted onto a former ‘Continental’ 62’ 0” underframe built at Ashford October 193 for First 7372, this coach having its body destroyed by fire at Dover Marine in July 1935. As a result, it was allocated diagram number no. 739 which was amended to 743 when coach formed into 4 SUB unit no.4176.

The following table lists these vehicles in their final electric stock number series, with their original numbers and construction dates, type of lighting when new (G = gas, E = electric), their second LSWR number where applicable, their new SR number, the date the vehicle was withdrawn for conversion, the new electric stock number, the initial set allocation of the vehicle, diagram number No. and intermediate coupling type (RP = rubbing plate, CB = centre buffer).

Ex. SECR Coaches

The ex. SECR coaches used in Central Section sets 1121-1167 and a subsequent batch 1188-1194 are known, these coaches being converted for Trailer Set use at Ashford works from a batch of fifty five 46' long 8‑compartment thirds constructed between 1900 and 1907. These vehicles seated eighty, the compartment widths being 5' 7½" and were 49' 11" long over buffers. The vehicles were constructed in three batches, ten being built by Metropolitan Railway Carriage & Wagon Co. in 1900, a larger batch of thirty‑five by Oldbury Railway Carriage & Wagon Co. in 1901 and a further twenty by the SECR itself at Ashford in 1906/7. Bogie centres were at 31' 0" and the underframes were of composite steel/wood construction, there being detail differences in these between the three batches.

All were new with electric lighting and vacuum brakes, the MRC&W and the first twenty‑four of the ORC&W batches were also Westinghouse air‑piped, though this was removed from most of them by 1920. Coaches were all fitted with steam heating between 1911 and 1916. These coaches were all renumbered by the SR and were allocated the diagram number no. 46.

Prior to the formation of the SR, these coaches had been earmarked by the SECR as possible conversions to electric multiple unit vehicles and on formation of the SR, all but six of them were allocated numbers (8999-9057) in the ‘electric’ series. However, the adoption of the LSWR system of electrification in the early years of the SR electrification programme led to them not being included at this stage and they were then allocated further numbers in the ‘steam’ series, though three coaches did carry their intended ‘electric’ numbers, one being renumbered back into the ‘steam’ series, the other two retaining theirs. Not all coaches were renumbered before their conversion to Trailer Set vehicles, retaining their SECR numbers until conversion. Those never renumbered have their intended numbers shewn in brackets.

The large increase in electric stock required for the Central Section schemes in 1928 led to these vehicles again being considered suitable for use as electric stock, and fifty‑four were subsequently converted at Ashford works for use in Trailer Sets, this work involving the fitting of Westinghouse air brakes and electric heating and the provision of control jumpers. The coaches were then close coupled with an ex. LSWR 11‑compartment coach to form Trailer Sets 1121-1167 and 1188 during 1928 /1929, with additional sets 1189-1194 added in 1931. These conversions were to H.O. number 214 (1121-1167) or H.O. 516 (1188) and H.O. 585 (1189-1194), all being allocated the new diagram number no. 725. All this batch of conversions were fitted with a central buffer at what became the inner end of the set.

The following table lists these vehicles in their final electric stock number series, with their original numbers and construction dates, builder (MCW for Metropolitan, OCW for Oldbury and AFD for Ashford) their SR ‘steam’ number and where applicable, their first SR ‘electric’ number, the date the vehicle was withdrawn for conversion, the new electric stock number and the initial set allocation of the vehicle.

Ex. LBSCR Coaches

The ex. LBSCR coaches used in Trailer Sets are known, these being used in the 1925 ‘Guildford & Dorking’ sets 1025-1037, and the 1925 /1926 ‘Eastern Section’ sets 1051-1117, with subsequent conversions for the 1928 /1929 ‘Central Section’ sets 1168-1187. The coaches were taken from three main sources, 9‑compartment Thirds, either built new or converted from six‑wheeled bodies, conversions of former ‘AC’ electric vehicles modified and rebuilt for ‘DC’ use, and finally some further 9‑compartment Thirds from former bogie-block suburban sets, these being slightly shorter than the 9‑compartment coaches converted earlier from loose coaches.

A total of forty‑three ‘Rebuilt Thirds’ were rebuilt at Lancing in 1910 /1911 from 5‑compartment six-wheelers built between 1891 and 1897, their bodies being remounted onto a then standard LBSCR 54' steel underframe. A further four new matching compartments were then built to make up the 9‑compartment Third. The compartments of the original vehicle were 5' 10¼" wide whilst the new ones were 5' 11" between partitions. The six-wheelers had been gas lit and the new compartments were similarly equipped. Overall, these coaches now seated 90 and weighed about 23 tons. They were 54' long over bodywork and 8' 0" wide and were given the LBSCR diagram number No. 171, this becoming SR diagram number No. 72.

One prototype conversion at Brighton in 1907 utilised the bodies of two six‑wheelers, 495 & 558, the new coach taking the number 495. All these coaches were allocated ‘steam’ numbers by the SR but only six actually had these applied during overhaul in 1924 before the decision was taken to use them all as electric Trailer Set vehicles. Conversion to electric Trailer Set coaches took place at Lancing works in 1925 under H.O. order number 53 and involved fitting the vehicles with electric lighting and heating and provision of jumper connections at vehicle ends where these became the outer end of the Trailer Set.

The coaches already had Westinghouse air brakes so these did not require alteration, nor were the buffing arrangements changed as the Trailer Sets that these coaches were formed into remained loose coupled. These coaches were given the electric diagram number No. 724 and formed into sets 1051-1109 randomly after conversion, some being paired, whilst others were coupled to other similarly converted vehicles from purpose built 9‑compartment Thirds.

A large batch of one‑hundred & five 9‑compartment Thirds were built for the LBSCR, the first fifty being ordered from the Metropolitan Amalgamated Railway Carriage & Wagon Co. Ltd of Birmingham, these being delivered in 1911. A further twenty‑five were then built at Lancing during 1912 /1913 and a final batch of thirty, again from Lancing in 1921. These coaches were similar dimensionally to the ‘Rebuilt Thirds’ mentioned above, but all their compartments were of a standard width of 5' 10½" and they weighed 24 tons 2 cwt.

These coaches were equipped from new with electric lighting, though a few did not have dynamos. They were given the LBSCR diagram number No. 198, later SR diagram number No. 71. These coaches were allocated ‘steam’ numbers in the range 2186-2290 by the SR but only 23 overhauled during 1924 actually carried them, the remainder gaining their ‘electric’ numbers directly during conversion.

Once again conversion to electric working took place at Lancing where electric heating was installed and jumper connection boxes added at set ends. The 1921 built batch were converted first in 1925 for H.O. order number 67 and used in ‘Guildford & Dorking’ sets 1025-1037 being allocated to these in numbered pairs. Later conversions in 1925 /1926 for the ‘Eastern Section’ sets as part of H.O. order number 53 saw these coaches allocated to sets 1051-1110 & 1114 in random order and some were paired, others coupled to the ‘Rebuilt Thirds’ also being converted at this time. These coaches were allocated the diagram number No. 723.

As conversion of both types of 9‑compartment Thirds were running side by side, the converted coaches were given intermixed numbers in the range 8999-9120 as they were dealt with.

Coach numbers 9121-9132 were converted in 1926 at Lancing works to order number H.O. 136 for additional sets for the 1051-1117 batch of Trailer Sets for the ‘Eastern Section’ electrification. These coaches started life as 2^nd /3^rd Composites formed in bogie-block suburban carriage sets, these vehicles being close coupled with a centre buffer and rubbing plate arrangement. They were mounted on 50' steel underframes and had 9‑compartments, four former second-class at 5' 8½" wide and five former third class at 5' 2½" wide. These coaches weighed 21 tons (some weighed 22 tons when fitted with a dynamo) all having been built with electric lighting.

These coaches had been constructed either at Brighton or by the Birmingham Railway Carriage & Wagon Co. Ltd between 1898 and 1901. All were downgraded to all third class in 1911 and renumbered by the LBSCR into the Third number series, now being to diagram number No. 157.

Some of the bogie-block sets were disbanded from 1911 and others altered and fitted with long buffers to make them suitable for main line use, and all the coaches later selected for conversion to electric Trailer Set vehicles came from this type. All these thirds were renumbered by the SR being allocated numbers in the ‘steam’ series, but only two were actually renumbered thus during 1924, the remainder gaining their new ‘electric’ numbers directly during conversion. The SR allocated these vehicles diagram number No. 68, and this was amended into the electric series as 726 on conversion. These slightly shorter coaches were eventually formed into sets 1111-1113 & 1115-1117.

When the Trailer Sets which included many these coaches were reformed and close coupled from late 1934, the diagram numbers of the vehicles concerned were amended to reflect whether they were then fitted with either a rubbing plate or a centre buffer as follows:

Original diagram number	New diagram number (centre buffer)	New diagram number (rubbing plate)
723	736	735
724	737	738
726	734	733

The following table lists all these 9‑compartment Third coaches in their final electric coach number order, with their original numbers and construction dates, builder (BRCW for Birmingham RCW, BTN for Brighton, MCW for Metropolitan RCW and LANC for Lancing), the rebuilding date where six-wheelers had been rebuilt as bogie coaches, (all these were done at Lancing except the prototype at Brighton), the second LBSCR number when composites were downgraded to thirds, the SR ‘steam’ number where carried, the date the coach was converted for electric use (all conversions at Lancing), the new electric coach number, the set number the coach was initially formed into and the electric diagram number allocated.

At this time the LBSCR only recorded their new coaches every six months hence all the ‘New Dates’ are either Jun or Dec prefixed, actual building dates were more varied.

Note
Both former LBSCR Thirds 2121 & 2122 (under their SR numbers) are recorded as condemned at Lancing in 1931 /1932 and bodies broken-up, so the origins of electric trailers 9121 /9122 must have been different !

29	Coach converted from two six-wheelers (495 & 558) at Brighton.

A further forty ex. LBSCR coaches were converted for use in Trailer Sets in 1929/30, all being converted from redundant ‘AC’ electric stock displaced by the conversion of the ‘Central Section’ lines during 1928/9. These coaches were altered at Lancing works into further 9‑compartment Trailer Thirds and renumbered into the Trailer Set number series becoming coaches 9256-9295 and allocated in numbered pairs to sets 1168-1187, these sets then being used for later stages of the Central Section conversion to DC.

Conversion ‘CP’ Motor Brake Thirds

The bulk of the coaches used in Trailer Sets (thirty‑four) were converted from former ‘CP’ Motor Brake Thirds, these being 7‑compartment vehicles seating 70 with compartments 5' 11" wide. There was a driving cab and guard's compartment at one end, above which were the bow collectors, the roof being depressed over this area.

These coaches were 57' 7" long over buffers with 54' 0" body length and had the distinctive girder-trussed underframes first seen on the ‘SL’ stock. Overall width was 8' 0" as some of the tunnels on the Crystal Palace lines had restricted clearances. Bogie centres were set at 37' 0" with all four axles motored with 150hp Winter Eichberg motors, and these coaches weighed 51 tons 6 cwt in motor coach form and were to LBSCR diagram number number 282 which became SR diagram number No. 676.

All were built by the Metropolitan Amalgamated Railway Carriage & Wagon Co. Ltd of Saltley, Birmingham, thirty in 1911 and a further four added in 1912. These coaches were originally numbered 3231-3264 by the LBSCR and as with all the ‘AC’ stock were not allocated to fixed unit formations. All these coaches were allocated new numbers by the SR, between 8567-8600, most gaining these during overhauls at Lancing in the next few years.

Conversion to ‘DC’ Trailer Third coaches took place at Lancing and involved rebuilding the former driver and guard's compartments as two matching third compartments, the coaches then becoming 9‑compartment vehicles seating ninety. The two new compartments were slightly narrower than the original nine at 5' 9" wide and were located at the outer end of the set. The former motor bogies were replaced by LBSCR type trailer bogies and in their new form these vehicles now weighed 25 tons and were given the new diagram number  728 and renumbered again into the range 9256-9295.

Conversion ‘AC’ Driving Trailer Composites

The remaining six vehicles required to complete this batch of forty coaches were converted from former ‘AC’ Driving Trailer Composites, these coaches again being to the same dimensions as the MBTs with 54' long bodies on rod-trussed underframes, 57' 7" long over buffers with an overall width of 8' 0" and bogie centres at 37' 0". Two were taken from the coaches built in 1911 to run with the ‘CP’ Motor Coaches, one being constructed by Metropolitan, the other at Lancing.

They consisted of a driver's compartment, five third class compartments 5' 10¼" wide and three first class compartments 6' 6¾" wide. They weighed 24 tons and seated 24 first and 40 third and were to diagram number 282 (SR 791).

The remaining four came from subsequent batches of coaches built in 1914 /1915 at Lancing, two becoming further ‘CP’ stock, whilst the other two did not enter service as ‘AC’ stock until 1925, having been stored partly unfinished through the war and then fitted with steam heaters and used temporarily as steam hauled stock until 1924 when they were modified for use as AC driving trailers for the Coulsdon & Wallington electrification. These coaches were similar dimensionally to the 1911 pair but had four first class compartments 6' 6½" wide and four thirds 5' 8" wide and seated thirty-two first and forty third. These were LBSCR diagram number 285 (diagram number 100 when in use as steam stock) altered to 792 by the SR.

Conversion work on these at Lancing works involved altering the former driver's compartment to a 5-seat coupe compartment 4' 0¾" wide and downgrading the first class compartments to third, these coaches then seating 85 third. The two 1911 coaches gained the new diagram number 729 whilst the remaining four became diagram number 730. These sets were loose coupled with all the coaches retaining conventional side buffers at both ends.

The following table shows details of these coaches in their electric coach number order, with their original LBSCR numbers, date constructed and builder details (LANC for Lancing Works and MCW for Metropolitan), the SR ‘AC’ number where carried, the date the coaches taken to Lancing for conversion, their new ‘DC’ numbers, the set they were initially allocated to and their new diagram numbers.

Replacement coach 9140

One further ex. LBSCR coach was converted for use in ‘Central Section’ set 1152 whose 46' ex. SECR 8‑compartment coach was lost in an accident at Epsom Downs in July 1937. Conversion took place from December 1937 at Lancing works and the rebuilt vehicle was ready by July 1938 and formed into set 1152. This coach had a fascinating history, both the underframe and the body.

The 54' underframe came from a coach built at Lancing in December 1919 and intended as an ‘AC’ Driving Trailer Composite for the Coulsdon & Wallington scheme. This coach consisted of a driver's compartment, four first and four third compartments, the firsts being 6' 6½" in width, the thirds 5' 8" in width, to diagram number 284. The coach was numbered 4105 in the ‘AC’ series but was stored, partly completed until it was finished off in 1921 and fitted with steam heaters, entering service as a steam‑hauled coach and being renumbered into the ‘steam’ series as 6257 in October 1927. The unused driver's cab had the windows obscured.

In March 1931, coach 6257 (along with two others) was converted into a steam pull-push Driving Trailer Composite, the first-class compartment behind the disused cab being stripped out and merged with the cab section to form a combined driver's and guard's compartment 10' 8" long. Double doors were provided, the guard's door opening inwards and 1 ton of luggage was permitted.

The two end observation lights of the ‘AC’ design were retained, resulting in these three coach conversions being easily recognisable as other steam push‑pull coaches had four observation lights on the coach end.

The coach was then renumbered again, as 6939, given a revised diagram number No. 437 and formed with an ex. LSWR 8‑compartment Third as set 649. It was used mostly on the Eastern Section at Allhallows, Hythe and Westerham, but saw occasional use on the Central Section from Horsham working to both Guildford or Brighton.

Set 649 was then withdrawn in August 1937 and the bodywork of 6939 was removed and scrapped, the underframe then being available for further use.

The bodywork of the ‘new’ 9140 started life as a 54' bogie Third Brake 867 built at Lancing in June 1913 for four-set 78. This coach consisted of a large luggage area, 23' 11½" long with two pairs of double doors each side, the doors nearest the end of the coach opening inwards for the guard whilst the remaining three opened outwards. There were five third compartments (each 5' 10" wide) and the coach was to diagram number 202.

It had electric lighting from new and was used between London Bridge and Brighton or Hastings. The SR renumbered the coach 3968 in January 1927, in the meantime having equipped it with dual braking in 1925/1926 and formed it into three-set 826. The coach was then withdrawn from traffic in December 1937 and the body placed onto the underframe of similarly withdrawn 6939 in January 1938.

Conversion of the body then took place, the brake area being stripped and replaced with four new third compartments, the coach now being a 9‑compartment Trailer Third and given the unique diagram number 737. In this form the coach now seated ninety third and weighed 23 tons 8cwt. It was fitted with a centre buffer at one end.

Guildford & Dorking Stock
Sets 1025-1037

The extension of electrification to Dorking North & Guildford from 9^th July 1925 required further electric stock and twenty‑six 3-Car Motor units (nos.1285-1310) were ordered for this scheme along with a further thirteen Trailer Sets, these appearing as sets 1025-1037 to order number H.O. 67.

These sets were made up from conversions of LBSCR bogie Thirds built at Lancing in 1921 and the conversions were also carried out at this works. Each vehicle weighed 25 tons 12cwt, was 57' 7" long over buffers (54' 0" over bodywork) and seated ninety third in nine compartments. Bogie centres were at 37' 0" inset 8' 5½" from the coach end. These coaches were already fitted with Westinghouse brakes prior to conversion. Each compartment was 5' 10.9/16" wide except the centremost which was 5' 10½" wide.

Bodywork was wooden panels with overbeading and ventilation louvers above the door droplights, those on smoking compartments being a metal tube with vents at each end, those on non-smoking compartments being a wooden louvered cover with the vent along the bottom edge. LBSCR upholstery of red & black tapestry with full back cushions was retained and electric heating and lighting fitted to the pattern of the LSWR sets with the lamps in glass bowls. Each coach contained three non-smoking compartments, these being located as the second one in from each end and the centremost one.

The coaches remained loose coupled, overall set length was 115' 2" and they weighed 51¼ tons and seated one-hundred & eighty third-class. All coaches were allocated SR diagram number 723 despite there being detail differences between each one of the set in connection with the lighting supply arrangements. These sets were similarly modified between 1934 and 1938 to the 1001-1024 batch with a central lighting jumper fitted, then becoming common-user with the remainder of the Trailer Set fleet.

Diagram numbers were altered to 735 and 736 during this modification programme when the sets were modified with the centre buffer and three link chain coupling between coaches, the odd numbered vehicles gaining a rubbing plate (diagram number 735) whilst the even numbered vehicles gained a centre buffer (diagram number 736).

All sets survived the war and were withdrawn between 1946 and 1949, a few surviving until the end of diagrammed Trailer Set working on Monday 27^th September 1948, two bodies being grounded and three coaches appropriated for departmental use whilst a further two vehicles were converted to de-icing trailers and also taken into departmental stock. All the remaining bodies were broken-up at Lancing and the underframes cut-up shortly afterwards in the London area.

Set formations and disposal details were as follows:

Eastern Section Stock
Sets 1051-1117

The electrification of the Eastern Section suburban lines in 1925/1926 required a large increase in the quantity of electric stock to operate the new services. Stock authorised for this scheme was one-hundred and thirty four 3 Car Motor Units (nos.1401-1534), twenty-nine being newly built, the remaining one‑hundred and five being conversions of former SECR steam stock mounted on new standard 62' 0" underframes.

Also authorised as part of the scheme were a further sixty‑seven two-coach Trailers Sets, these appearing in 1925/1926 as sets 1051-1117, enabling sixty‑seven eight-coach trains to be available for the Eastern Section requirements.

These conversions were ordered in two batches, H.O. 53 for sets 1051-1109 & H.O. 136 for sets 1110-1117.

The vehicles converted for these sets at Lancing works were numbered 8999-9132 and came from several different sources. Vehicles 8999-9120 in sets 1051-1110 & 1114 had two main origins, forty‑three of them were former six-wheelers built between 1891 and 1899 at Brighton and mounted on new underframes at Lancing in 1910/1911 with four newly built compartments added (they still retained their gas lighting), whilst a further seventy‑nine were from new construction between 1910-1913 and a further batch in 1921, twenty‑nine were built at Lancing and fifty came from the Metropolitan Amalgamated Railway Carriage & Wagon Co. Ltd.

These coaches were all 9‑compartment Thirds seating 90 and vehicles were 57' 7" long over buffers (54' body length) and weighed 23 tons 8cwt. Bogie centres were at 37' and overall width 8'. These coaches were new with electric lighting.

Compartments were 5' 10⁹/₁₆" in width (except the centremost one which was 5' 10½" wide) in the 9‑compartment coaches built as such, but the ex. six‑wheeled bodies varied with the original five compartments being 5' 10¼" wide and the newer ones added being 5' 11" in width. The converted six‑wheelers became SR diagram number 724 whilst the bogie coach conversions were to diagram number 723.

The final twelve vehicles converted were 9121-9132 (going to sets 1111-1113 & 1115-1117), these having been built between 1899 and 1901, seven by the Birmingham Railway Carriage & Wagon Company and five at Brighton. These coaches were built as bogie 2^nd /3^rd Composites and close coupled as part of bogie-block suburban stock. All were downgraded to Third-class in 1911 with each of the compartments then seating ten. These coaches were 50' over body, 8' in width and had bogie centres at 33' and weighed 21 tons 17cwt. The former second class compartments were 5' 8½" wide whilst the original thirds were 5' 2½" wide, and these coaches were allocated the diagram number 726.

Conversion work involved fitting jumper connections at set ends, conversion to electric lighting where necessary, installation of electric heating and through electrical cabling. Many former LBSCR features were retained such as wire racks, air extractors and door & commode handles; the bodies were wooden panelled with wooden beading over panel joints and the seating was ‘full back’.

These sets remained loose coupled and were 115' 2" long overall, weighed 46 tons 16cwt and seated one-hundred & eighty third-class, though 1111-1113 & 1115-1117 were only 107' 2" long and weighed 43 tons 14cwt. An odd feature was that the ventilation louvres on the doors were of a different pattern for smoking compartments (a metal tube with vents at each end) and non-smoking compartments (a wooden cover with the vent along the bottom edge). Each coach contained three non-smoking compartments, located as the second from each end and the centremost one.

Many of these sets were subject to reforming between October 1934 and May 1938 when one of the LBSCR coaches was displaced by a newly converted former LSWR 10‑compartment conversion mounted onto a standard SR 62' 0" underframe. The displaced former LBSCR vehicles were used to form further Trailer Sets, being coupled with further fresh ex. LSWR 10‑compartment conversions. Other LBSCR coaches were swapped between sets at this time.

Wartime Damage & Reformations

Some sets were lost to war damage and the survivors were withdrawn between 1943 and 1948, the LBSCR coaches being scrapped, though a number of grounded bodies survived much longer, whilst the LSWR coaches were used to augment 3 Car Motor Units to 4 SUB, most of these later having their bodies scrapped and the SR type underframes were then reused for 4 EPB vehicle construction.

When reformed with an ex. LSWR trailer, the coaches were then close-coupled with the centre buffer and three-link chain arrangement. This also entailed altering the diagram numbers of the coaches, those originally to diagram number 723 becoming 736 (buffer) or 735 (rubbing plate), those originally to diagram number 724 becoming 737 (buffer) or 738 (rubbing plate) whilst the shorter diagram number 726 vehicles became 734 (buffer) or 733 (rubbing plate).

Original formations of Trailer Sets 1051-1117 are shewn in the list below prior to the 1934 onwards reforming with LSWR coaches. The thirty‑four vehicles displaced during the reforming were used, along with a further LSWR coach to form new Trailer Sets numbered 989-1000, 1038-1050, 1118-1120 & 1195-1200.

Coaches with the shorter underframes are marked with * after the vehicle number, whilst the six‑wheeled body conversions are marked with # after the vehicle number. The ‘new’ date is the date the LBSCR coaches were taken to Lancing for conversion, the entry to traffic of the new Trailer Set being a few weeks later, whilst the date of the reformation shewn is that which the ex. LSWR replacement coach was withdrawn from traffic for conversion, the actual date of return to traffic of the reformed Trailer Set being shortly afterwards. The displaced trailer was that shewn in the right‑hand column of the set formation list, and reformed sets are shewn again later in a second list in their new formations. A number of sets had both their original coaches transferred to ‘new’ sets, in these cases both vehicles are shewn in the ‘Displaced TT’ column with the left-hand one first in each case.

Individual Set Notes

Note	A number of coaches are shewn as disposed of by ‘London Bridge’, it is believed that the job of breaking these was allocated to London Bridge C&W and was carried out in the London area (possibly at Ewer Street or Rotherhithe Road?) though breaking-up is unlikely to have been carried out at London Bridge itself.

Reformed Sets 1051-1117

Between October 1934 and May 1938, thirty‑four of the sixty‑seven Trailer Sets converted for the Eastern Section electrification were reformed. These sets originally consisted of two ex. LBSCR 9‑compartment coaches, loose coupled and seated one-hundred & eighty third-class. Most were 115' 2" long and weighed 46 tons 16cwt, but a few (1111-1113 and 1115-1117) had slightly shorter bodies and were 107' 2" long and weighed 44 tons 14cwt.

The ‘new’ coaches converted for these sets were former LSWR 8‑compartment bogie Thirds built between 1894 and 1902 converted at Eastleigh and mounted onto new SR 62' 0" underframes. The bodies were lengthened with two matching additional compartments, the 10‑compartment coaches now seating one-hundred third class. The original compartments were 5' 10.3/8" in width, the new ones were 6' 10.7/8" wide and were located at the end of the coach at the centre of the Trailer Set. These two new compartments only had a half-partition, i.e., to top of seat backs.

These coaches weighed 27 tons and were 64' 8" long (62' 0" over bodies) and were to diagram numbers 731 and 732. Westinghouse air brakes were fitted and electric lighting and heating installed, operated from the adjacent 3 Car Motor Units. These coaches were then close‑coupled to an ex. LBSCR vehicle giving a revised overall length of 121' 5" for most sets, though those coupled to one of the shorter vehicles were only 117' 5" long. Overall set weight was now 50 tons 8cwt (48 tons 17cwt for the shorter LBSCR vehicle sets), and they now seated one-hundred & ninety third-class.

The newly converted coaches were allocated to the next set due in for overhaul as they were outshopped, and not in any particular number order.

The date of the reformation shewn is the date that the ex. LSWR coach was withdrawn for conversion, the actual date to traffic of the reformed Trailer Set being a short while later. The diagram numbers of the ex. LBSCR vehicles, previously 723 /724 /726 variously, were then amended to 736 /737 /734 respectively when modified with a centre buffer at one end or to 735 /738 /733 respectively when modified with a rubbing plate at one end.

The three compartments at the outer end of each 10‑compartment coach were smoking, the four centremost ones being three non-smoking with a further smoking one splitting them two & one.

It is possible that the reason for these reformations was due to the requirement to introduce more vehicles to traffic as Trailer Sets, but as all these later conversions were now mounted on 62' 0" underframes, the overall length of sets formed of two such vehicles at 129' 4" (see sets 1195-1198) meant that an 8-car train was now 516' 8" long and exceeded the platform length or clearance of track circuit block joints at certain ‘tight’ locations.

A similar problem arose again in later years when the first BR type 2 EPB units were introduced with buckeye couplers between vehicles and these had to be modified with the centre-buffer and three link chain arrangement to reduce their overall length.

It also had the effect of standardising the seating capacity of these sets with the 1928/1929 Trailer Sets and subsequent conversions.

Some of the later LSWR coaches converted during the final two phases of reforms were flush panelled in steel and looked much more modern than the LBSCR vehicle attached to it, these are marked with an ‘f’ after the vehicle number.

These reformations ran alongside the creation of ‘new’ Trailer Sets in the batch 1038-1050 from July 1935 to July 1936, these sets being similar to the reformed ones and created by using a further newly converted ex. LSWR coach coupled to a displaced ex. LBSCR vehicle from reformed sets in the 1051-1117 series, and were numbered downwards from 1050 as they were introduced.

The newly converted ex. LSWR coaches were mixed between the two batches. Coaches for this batch of conversions were ordered in three sub-batches to H.O. 844 (those converted during the summer) and H.O. 853 (those converted towards the end of 1935) with a final pair to H.O. 901 in July 1936, this order also including further vehicles for the next batch. This process was repeated again in March /April 1937 with ‘new’ sets 1118-1120 & 1199 being formed (again with vehicles from order No. H.O. 901).

A further order to H.O. 929 followed in summer 1937 allowing the creation of sets 998-1000 & 1200, and the final phase of the conversions was completed using vehicles authorised to order No. H.O. 965 which saw the appearance of sets 989-997 between January and May 1938.

Wartime Damage & Reformations

These sets started to be withdrawn during the latter part of the war, the ex. LBSCR coaches being scrapped, (some had bodies grounded for wartime use) whilst the ex. LSWR coaches were used to augment 3 Car Motor Units of the original 1915 LSWR batch to form 4 SUB units in the 41xx series. Their diagram numbers were then altered from 731 or 732 to 741 or 740 respectively. Two with non-standard underframes (9078 and 9298) became diagram 739, these being altered to 743 when formed into 4 SUB units.

Coaches with the shorter underframes are marked with ‘*’ after the vehicle number. Scrapping details of the LBSCR coaches are shewn in the Individual Set Notes, those bodies grounded elsewhere are also shewn.

Individual Set Notes

Note	A number of coaches are shewn as disposed of by ‘London Bridge’, it is believed that the job of breaking these was allocated to London Bridge C&W and was carried out in the London area (possibly at Ewer Street or Rotherhithe Road?) though breaking-up is unlikely to have been carried out at London Bridge itself.

Central Section Stock
Sets 1121-1167

The Central Section electrification scheme of 1928 /1929 required a large increase in the amount of DC electric stock to operate the new services covering the extension of electrification and the simultaneous conversion of the ex. LBSCR ‘AC’ system to DC operation.

3 Car Motor Units nos.1601-1701 were authorised comprising three batches of units converted from ex. SECR, LBSCR and LSWR steam hauled stock respectively and a similar conversion of ex. SECR and LSWR steam hauled suburban coaches displaced by the 1925 electrifications on both sections were used to form forty‑seven two-coach Trailer Sets numbered 1121-1167 ordered to H.O. 214.

These Trailer Sets consisted of one ex. SECR 8‑compartment 46' bogie coach close‑coupled to an 11‑compartment ex. LSWR coach, a former 51' 7” compartment Brake Third mounted onto a new SR 62' 0" underframe from Lancing with four additional compartments added, two replacing the former brakevan area.

Conversion work was carried out at Ashford works and electrical work at Brighton, the ex. SECR coaches being little altered and being similar internally to the ‘1401’ batch of 3 Car Motor Units. These vehicles had been constructed between 1900 and 1907, some at Ashford, some from MRC&W and others from ORC&W, and were 46' long over bodywork and seated eighty third-class with each compartment being 5' 7½" wide. Weighing 22 tons 9cwt all coaches were to diagram number 725. Bogie centres were at 31' 0" inset 7' 5½" from the coach end.

The ex. LSWR coaches were rebuilt from 7‑compartment Brake Thirds with two additional compartments added at one end and two replacing the brakevan area. Seven compartments were 5' 6" wide and the four new ones (at the outer end of the set) were 5' 6½" wide. These coaches had all been built at Eastleigh between 1902 and 1912 as the end vehicles of bogie-block suburban trains and already had a close-coupling arrangement at the non-brakevan end. These coaches seated one-hundred & ten third-class, weighed 26 tons 6cwt and were to diagram number 727. Overall set capacity was therefore one-hundred & ninety third-class; the sets were 113' 8" long and weighed 48¾ tons. The SECR coach in set 1127 had matchboarded sides on conversion, probably fitted during a repair in the early 1920's.

The usual other alterations involved modifying the coupling to the centre- buffer and three link chain at the middle of the set, conversion of braking to the Westinghouse air system, installation of electric heating, alteration of the lighting to work from the adjacent 3 Car Motor Unit and fitting of jumper cables & connections at set ends. Installation of through cabling and local control of heating and lighting was also carried out. The 8‑compartment coaches were those fitted with centre-buffers whilst the 11‑compartment coaches were fitted with rubbing plates.

Non-smoking compartments were located as the third from each end of the 8‑compartment coaches and the fourth/fifth from each end of the 11‑compartment coaches.

These sets began to be withdrawn during the war and the ex. SECR vehicles scrapped, their bodies mostly at Lancing and the underframes in the London area, though a number were grounded for wartime use as ARP and Home Guard hutments. The ex. LSWR coaches were mostly reformed into 3 Car Motor Units, the augmented 4 SUB then being renumbered into the 42xx series. Their tare weigh was amended to 28 tons when modified for use in 4 SUB units.

Individual Set Notes

Note	A number of coaches are shewn as disposed of by ‘London Bridge’, it is believed that the job of breaking these was allocated to London Bridge C&W and was carried out in the London area (possibly at Ewer Street or Rotherhithe Road?) though breaking-up is unlikely to have been carried out at London Bridge itself.

1929 /1930 Stock
Sets 1168-1187

The Central Section electrifications of 1928 and 1929 steadily displaced the ex. LBSCR ‘AC’ stock which then was stripped of its electrical equipment at Peckham Rye. Forty of these vehicles were then converted at Lancing works into Trailer Sets and altered to be able to work with 3 Car Motor Units in the usual manner for Trailer Sets. Thirty‑four of these vehicles were from ex. Crystal Palace ‘CP’ stock Motor Brake Thirds and two ex. ‘CP’ Driving Trailer Composites were also used along with four ex. Coulsdon /Wallington ‘CW’ Driving Trailer Composites.

Converted ‘CP’ Motorcoaches

The ex. ‘CP’ motorcoaches were mounted on the heavy girder-trussed underframes which were a distinctive feature of this stock, they originally had a cab and van area and seven third-class compartments. During conversion, the cab and van area were altered into two further third- class compartments giving a 9‑compartment coach seating ninety third-class.

The original seven compartments were 5' 11" wide whilst the two additions were 5' 9" wide and were located at the outer end of the set. Both the former motor bogies were ex. changed for LBSCR type trailer bogies surplus from earlier conversions of ex. LBSCR vehicles for 3 Car Motor Units.

Following conversion, these coaches weighed 26 tons 9cwt, were 54' 0" long over bodies and 57' 7" long over buffers. Bogie centres were at 35' 0" inset 9' 5½" from the coach ends. Retaining their side buffers at both ends, they were loose coupled within the set and allocated diagram number 728.

Converted ‘CP’ /’CW’ Driving Trailer Composites

Six vehicles were converted from former Driving Trailer Composites, two from the ‘CP’ fleet and the remaining four using vehicles intended for part of the ‘CW’ fleet, two being used instead in the ‘CP’ stock and the remaining two (after a period in store during the war) being temporarily used as steam hauled coaches prior to being altered back to AC operation as part of the ‘CW’ fleet; the intended cab having opaque windows installed whilst in use as steam stock.

As converted, the former driving cab became a 4' 0½" wide five-seat coupe compartment, followed by three 6' 6¾" wide compartments and five 5' 10¼" compartments, these 8½ compartment vehicles seated eighty-five third-class, their former first- class compartments being downgraded. Weighing 25 tons 11cwt each was also 57' 7" long; bodies were again 54' 0" long and bogie centres were at 37' 0" inset 8' 5½" from the coach end.

They were mounted on more conventional underframes, the two ‘CP’ vehicles being to diagram number 729, the remaining four ‘CW’ vehicles to diagram number 730. One of these vehicles were allocated to each of sets 1181-1186 which therefore seated five fewer than the remainder. The compartment dimensions differed slightly between the ex. ‘CP’ and ex. ‘CW’ conversions (exact details unknown). Overall, these sets seated one-hundred & eighty third-class, weighed 52 tons 18cwt and were 115' 2" long (with the exception of 1181-1186 which seated one-hundred & seventy-five and weighed 52 tons).

These sets were ordered in four separate sub-batches, H.O. 375 covering sets 1168-1178, H.O. 399 for sets 1179 & 1180, H.O. 455 for sets 1181-1186 and H.O. 516 for set 1187 (this order also covered set 1188 of the next batch of sets).

There were three non-smoking compartments in each coach, arranged as the second from each end of the coaches and also the centremost compartment.

One set was written off during the war and a further one by accident damage, the remainder stayed in traffic until withdrawn for scrapping between 1945 and 1948, two lasting until the end of Trailer Set workings on 26-Sep-48. Following withdrawal, some electrical stripping was carried out at Coulsdon North and most coaches had their bodies scrapped at Lancing and the underframes cut‑up in the London area.

Set formations were as follows, the 8½‑compartment coaches being marked with an ‘*’

1930/1931 Stock
Sets 1188-1194

The extension of electrification during 1930 led to the need for more Trailer Sets, one additional set (1188) being authorised nominally for the Central Section as part of H.O. 516 (this also included set 1187 of the previous batch), and a further six as additional stock (1189-1194) to order number H.O. 585.

These sets were resourced from the same vehicles used in the earlier conversions in 1929 for sets 1121-1167 and were delivered in July 1930 (1188) and early in 1931. They consisted of one ex. SECR 8‑compartment bogie coach close‑coupled to an 11‑compartment ex. LSWR coach, a former 7‑compartment 51' bogie Brake Third mounted onto a new SR 62' 0" underframe from Lancing with four additional compartments added, two replacing the former brakevan area.

Conversion work was again carried out at Ashford works with finishing off and repainting completed at Brighton, the ex. SECR coaches being little altered and being similar internally to the ‘1401’ batch of 3 Car Motor Units. These vehicles had been constructed between 1900 and 1906, mostly at Ashford though some were from outside contractors, and were 46' long over bodywork and seated 80 third and weighed 22 tons 9cwt and were to diagram number 725.

The ex. LSWR coaches were rebuilt from 7‑compartment 51' Brake Thirds with four additional compartments added at one end, two of which replaced the former brakevan area. These coaches seated one-hundred & ten third-class and weighed 26 tons 6cwt and were to diagram number 727. Overall set capacity was therefore one-hundred & ninety third-class. The sets were 113' 8" long and weighed 48¾ tons.

The usual other alterations involved modifying the coupling to the centre-buffer and three-link chain at the middle of the set, conversion of braking to the Westinghouse air system, installation of electric heating, alteration of the lighting to work for the adjacent 3 Car Motor Unit and fitting of jumper cables and connections at set ends. Installation of through cabling and local control of heating and lighting was also carried out. The 8‑compartment coaches were fitted with a centre buffer whilst the 11‑compartment coaches were fitted with rubbing plates.

The 8‑compartment coaches contained two non-smoking compartments located as the second from each end of the coach whilst the 11‑compartment coach contained four, located as the third/fourth from each end.

These sets began to be withdrawn during the war and the ex. SECR vehicles scrapped, their bodies at Lancing and underframes in the London area, and the ex. LSWR coaches were reformed into 3 Car Motor Units, the augmented 4 SUB then being renumbered into the 41xx and 42xx series.

1934 Stock
Sets 1195-1198

To run with the eleven 3 Car Motor Units ordered during November 1933 for the Sevenoaks electrification, a further four Trailer Sets were authorised to order number H.O. 791, these appearing in late 1934 as sets 1195-1198.

These sets were formed of two LSWR 8‑compartment bogie Thirds built between 1894 and 1902, made up to ten compartments by a further two added during conversion at Eastleigh where they were mounted onto new 62' 0" underframes from Lancing. The original compartments were 5' 10.3/8" wide whilst the two new ones were wider at 6' 10.7/8", these being located at the end of the coach coupled to the outer vehicle of the set.

Each coach weighed 27 tons after conversion and seated 100 third. These sets were close‑coupled giving an overall length of 129' 3" and they had full back seating with loose cushions and seated 200 third overall, with a weight of 54 tons. They were to diagram number numbers 731 (those fitted with rubbing plates) and 732 (those fitted with centre-buffers). Finishing off work and repainting and renumbering was carried out at Lancing works. Both coaches had three non-smoking compartments, these being the three of the centremost four compartments, split two & one by a smoking compartment.

The use of two vehicles on 62' 0" underframes made these sets longer than the earlier Trailer Sets and when coupled to two 193' 8" 3 Car Motor Units gave an 8-coach train a length of 516' 8" which possibly caused problems at certain locations where platform length clearances were tight, such as the bay platforms at St Pauls. A general review of the Trailer Sets was made and a re-arrangement of thirty-four of the earlier sets of the 1051-1117 batch converted in the 1925 Eastern Section electrification and formed of two ex. LBSCR coaches loose coupled was decided upon.

It was then decided to reform most of these sets with one ex. LBSCR conversion close coupled to a newly converted ex. LSWR 10‑compartment conversion identical to the vehicles converted for this batch of sets. After a very short period in their new formations, these four sets were reformed and exchanged one of the vehicles with one from an earlier set. The replacement vehicles for three of them were 9130 /9131 /9132 converted in 1925 for sets 1115-1117, these having been built in 1900/1901, one at Brighton, the other two by the Birmingham Railway Carriage & Wagon company as bogie 2^nd /3^rd composites.

All had been downgraded to third-class in 1911 with each of the compartments then seating ten. These coaches were 50' over body, 8' in width and had bogie centres at 33' and weighed 21 tons 17cwt. The former second class compartments were 5' 8½" wide whilst the original thirds were 5' 2½" wide.

The fourth vehicle involved in the exchange was 9027, a similar 9‑compartment LBSCR conversion though with a slightly longer body at 54', with bogie centres at 37' and compartments 5' 10½" wide. This coach weighed 23 tons 8cwt and was included in set 1198 making it both longer and heavier than the first three.

All were modified to be close-coupled to the ex. LSWR coach altering their diagram number numbers from 726 to 733 (coaches 9130 and 9132 fitted with rubbing plates), 726 to 734 (coach 9131 fitted with centre-buffer) and 723 to 736 (coach 9027 fitted with centre buffer).

In their new form, these sets now seated one-hundred & ninety, were 117' 6" long and weighed 48 tons 17cwt (except for 1198 which was 121' 6" long and weighed 50 tons 8cwt). When these sets were withdrawn the ex. LBSCR coach was scrapped, possibly at Lancing, the ex. LSWR coach was used to augment 3 Car Motor Units to 4‑SUB in the 41xx series; their diagram number numbers being amended to 740 (when fitted with centre buffer) or 741 (when fitted with rubbing plate). Coaches with the shorter underframes are marked with ‘*’ after the vehicle number.

Reformed Sets July 1935 – July 1936
Sets 1038-1050

This batch of Trailer Sets were formed between July 1935 and July 1936 using further newly converted ex. LSWR 8‑compartment bogie Thirds lengthened to ten compartments during conversion at Eastleigh and mounted on new SR underframes of 62' 0" length from Lancing. These vehicles were to diagram numbers 731 (when fitted with rubbing plate) and 732 (when fitted with centre-buffer). The other vehicle was an ex. LBSCR 9‑compartment vehicle removed from one of the earlier Trailer Sets in the 1051-1117 series, these vehicles being themselves replaced in these earlier sets by newer ex. LSWR 10‑compartment conversions.

The vehicles were close coupled, requiring modifications to the LBSCR vehicle which had been loose coupled in the earlier sets and a change in their diagram numbers from 723 /724 /726 to 736 /737 /734 respectively when fitted with centre buffers or to 735 /738 /733 respectively when fitted with rubbing plates. As converted these sets seated 190 and were 121' 6" long and weighed 50 tons 8cwt.

Each 9‑compartment coach retained three non-smoking compartments located as the second from each end of the coach and the centremost compartment, whilst the 10‑compartment coach also had three non‑smoking compartment, these being three of the four centremost compartments being split two & one by a smoking compartment.

Sets 1049 and 1050 both included one of the 49' body ex. LBSCR coaches, these two sets being 117' 6" long and weighing 48 tons 17cwt. The donor sets of the ex. LBSCR coaches are shewn below. The ‘formed date’ of these sets is the date when the ex. LSWR coach was withdrawn from traffic for conversion and the sets entered service shortly afterwards.

Planning was already underway to discontinue the use of Trailer Sets and the onset of war accelerated these plans, with the sets being withdrawn, the LBSCR coaches for scrapping, the bodies at Lancing and the underframes in the London area, though some had their bodies grounded for wartime purposes, usually ARP or Home Guard hutments. The recently converted ex. LSWR coaches were then used to begin the augmentation programme of the 3 Car Motor Units to 4 SUB units, their diagram numbers being amended at this time, those of 731 (rubbing plate fitted) becoming 741, those of 732 (centre buffer fitted) becoming 740.

Reformed Sets March 1937 to May 1938
Sets 989-1000, 1118-1120 & 1199 /1200

The programme of alterations to the Trailer Sets begun in 1935 using newly converted ex. LSWR 8‑compartment Thirds rebuilt to ten compartments and mounted on a new SR 62' 0" underframe from Lancing was continued in 1937/8. A batch were converted in February /March 1937 to order number H.O. 901, sets 1118-1120 & 1199 appearing, followed by a further batch in July 1937 to order number H.O. 929. these being sets 1200 & 998-1000. The final batch from January to May 1938 were to order number H.O. 965 and appeared as sets 989-997. Some of these conversions in the last two batches again had flush steel panelling.

These sets seated one-hundred & ninety third-class, were 121' 6" long and weighed 50 tons 8cwt. The donor sets of the ex. LBSCR coaches are shewn below. The number range of the existing Trailer Sets from 1001-1200 was almost all used with existing sets, these reformed sets filling the odd gaps in the series and having to be projected back into the loco‑hauled coaching stock set number series from 1-1000.

Diagram number numbers were again complex. with the 10‑compartment coaches being variously to diagrams 731 (rubbing plate fitted) or 732 (centre-buffer fitted) and the 9‑compartment ones being altered on conversion from 723 & 724 to 735 & 738 respectively when rubbing plate fitted or 736 & 737 respectively when centre-buffer fitted.

The ‘formed date’ of these sets is the date the former LSWR coach was withdrawn from traffic for conversion, the Trailer Set then entering traffic shortly afterwards.

As with the previous batch of sets, these began to be withdrawn during the war and the LBSCR coaches scrapped and the LSWR coaches then being used to augment 3 Car Motor Units to 4 SUB with their diagram numbers altered from 731 to 741 and 732 to 740 respectively. Set 998 was the very last Trailer Set to be overhauled in May 1947.
