List of British Rail electric multiple unit classes

This page lists every electric-powered multiple unit allocated a TOPS classification or used on the mainline network since 1948 (i.e. British Railways and post-privatisation). For a historical overview of electric multiple unit development in Great Britain, see British electric multiple units.

British Rail operated a wide variety of electric multiple units for use on electrified lines:

  • AC units operate off 25 kV alternating current (AC) from overhead wires. Where clearances for the overhead wires on the Great Eastern Main Line and London, Tilbury and Southend railway routes were below standard, a reduced voltage of 6.25 kV AC was used. The Midland Railway units used 6.6 kV AC. Under the computer numbering, AC units (including mixed-voltage units that can also work off a DC supply) were given a class in the range 300-399.
  • DC units operate off 650-850 V direct current (DC) from a third rail on the Southern Region and North London, Merseyside and Tyneside networks. The Manchester-Bury Railway line used 1,200 V DC from a side-contact third rail. The Manchester South Junction & Altrincham and "Woodhead" and initially the Great Eastern Railway routes used 1,500 V DC from overhead wires. Under the computer numbering, DC units were given a class in the range 400-599.

Southern Region units

The Southern Railway and its successor, the Southern Region of British Rail, used three letter codes to classify their DC EMU fleets, as shown after the TOPS class numbers. Southern Region EMUs were classified in the 400 series under TOPS.

Other DC units

The 500 series classes were reserved for miscellaneous DC EMUs not from the Southern Region. This included the DC (third/fourth rail) lines in North London, Manchester and Merseyside and the OHLE lines in Greater Manchester. The DC electric network around Tyneside had been de-electrified by the time TOPS was introduced, and the stock withdrawn or transferred to the Southern Region.

Battery electric multiple unit (BEMU)

The original BEMU was a one-off unit, withdrawn before the introduction of TOPS.

A new generation battery EMU (called an Independently Powered Electric Multiple Unit) was created in 2014, converted from a Class 379.

Non National Rail units

All rail vehicles operating on part of the National Rail network are required to be given TOPS codes. For this reason, London Underground, Sheffield Supertram and Tyne & Wear Metro trains have their own TOPS classes:

Class Info Image Notes
Class 398 Transport for Wales tram-train stock Planned use on Valley Lines services with street running through Cardiff
Class 399 Sheffield Supertram tram-train stock Will be used for a trial service to Rotherham via the Dearne Valley line
Class 499 (II) London Underground rolling stock Classification given to all London Underground stock operating on Network Rail, regardless of line
Class 994 Tyne & Wear Metro rolling stock Used for operation between Pelaw and Sunderland
