The Southern Railway created classification and numbering systems for its large fleet of electric multiple units, perpetuated by the Southern Region of British Rail until the early 1980s, when the impact of TOPS was felt. Some stock is still allocated Southern-style classifications in a semi-official manner.
The Southern Railway (SR) gave the designations 4-COR, 4-RES, 4-BUF and 4-GRI to the different types of electric multiple unit built to work the route between London Waterloo and Portsmouth Harbour. The 4-COR type units survived long enough in British Rail ownership to be allocated TOPS Class 404. The COR designation had previously been used for the 6-PUL units and was reused by them during World War II when the Pullman car was stored, but this stock was different from the 4-COR units.
The British Railways Class 24 diesel locomotives, also known as the Sulzer Type 2, were built from 1958 to 1961. One hundred and fifty-one were built at Derby, Crewe and Darlington, the first twenty of them as part of the British Railways 1955 Modernisation Plan. This class was used as the basis for the development of the Class 25 locomotives.
The British Rail Class 487 electric multiple units were built by English Electric in 1940, for use on the Waterloo & City line.
The Southern Railway (SR) gave the designations 6 PUL, 6 CITY and 6 PAN to electric multiple units built to work the routes between London and Brighton, West Worthing and Eastbourne. None of these units survived long enough in British Rail ownership to be allocated a TOPS class number. The 6 PUL units were designated 6 COR until 1935.
The Southern Railway (SR) gave the designation 2-BIL to the DC third rail electric multiple units built during the 1930s to work long-distance semi-fast services on the newly electrified lines from London to Eastbourne, Portsmouth and Reading. This type of unit survived long enough in British Rail ownership to be allocated TOPS Class 401.
The Southern Railway (SR) gave the designation 4-LAV to the electric multiple units built to work the semi-fast services on the route between London and Brighton. None of these units survived long enough in British Rail ownership to be allocated a TOPS class.
2-WIM was the designation given, by Southern Railway (SR), to a 4-strong fleet of electric multiple units, dedicated for use on the ex-LBSCR West Croydon to Wimbledon Line, using the headcode 2. None of these units survived long enough in British Rail ownership to be allocated a TOPS class.
The Southern Railway (SR) gave the designation 2-SL to the small fleet of electric multiple units dedicated for use on the South London lines. None of these units survived long enough in British Rail ownership to be allocated a TOPS class. In Southern Railway/Region days, they mainly spent their lives as 2-car units on the ex-LBSCR Wimbledon-West Croydon Line with head code 2. They were distinctive, because they retained their flat roofs over the driving cabs, where the pantographs were originally situated.
The Southern Railway (SR) gave the designation 2-NOL to the electric multiple units built during the 1930s from old London and South Western Railway carriage bodies on new underframes. None of these units survived long enough in British Rail ownership to be allocated a TOPS class.
The British Rail Class 508 (4PER) was a type of electric multiple unit (EMU) passenger train built by British Rail Engineering Limited, at Holgate Road carriage works, York, in 1979 and 1980. They were a variant of British Rail's standard 1972 design for suburban EMUs, eventually encompassing 755 vehicles and five classes (313/314/315/507/508). They mostly worked on the Merseyrail network from 1982 until withdrawal on 16 January 2024.
The British Rail Class 33, also known as the BRCW Type 3 or Crompton, is a class of Bo-Bo diesel-electric locomotives, ordered in 1957 and built for the Southern Region of British Railways between 1960 and 1962.
British Rail's Class 27 comprised 69 diesel locomotives built by the Birmingham Railway Carriage and Wagon Company (BRCW) during 1961 and 1962. They were a development of the earlier Class 26; both were originally classified as the BRCW Type 2. The Class 27s were numbered D5347-D5415.
The British Rail Class 302 was a type of electric multiple unit (EMU) introduced between 1958 and 1960 for outer suburban passenger services on the London, Tilbury and Southend line. This class of multiple unit was constructed using the Mark 1 bodyshell and was slam-door.
The British RailClass 414 were two-car electric multiple units that were built between 1956 and 1963. They were withdrawn in 1995.
The British Rail Class 506 was a 3 carriage electric multiple unit (EMU) built for local services between Manchester, Glossop and Hadfield on the Woodhead Line, which was electrified in 1954 on the 1,500 V DC overhead system.
Reading Southern railway station is a former railway station in Reading, Berkshire, England, located to the south of Reading General station on the Great Western main line.
The Southern Railway (SR) and the British Railways used the designation Sub to cover a wide variety of electric multiple-unit passenger trains that were used on inner-suburban workings in the South London area. The designation 'Sub' was first officially used in 1941 to refer to newly built 4-car units. However, during the 1940s large numbers of earlier '3-Car Suburban Sets' were increased to four cars by the addition of an 'Augmentation' trailer, and became part of the 4-Sub category. The SR and BR (S) continued to build or else rebuild 4-car units to slightly different designs which became part of the 4-Sub Class. Many of these later examples survived in passenger use until late 1983, by which time British Rail had allocated to them TOPS Class 405.
