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. 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 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 were given a class in the range 300-399.
- DC units operate off 650-850 V direct current 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.

DC EMUs
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.Pre-Nationalisation

Other DC units
The 500 series classes were reserved for miscellaneous DC EMUs not from the Southern Region. This included the DC 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 The DC electric network around Tyneside had been de-electrified by the time TOPS was introduced, and the stock withdrawn or transferred to the Southern Region.Class 507 unit no. 507009 at Liverpool Central railway station
