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). 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.

Other DC units

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 The DC electric network around Tyneside had been de-electrified by the time TOPS was introduced, and the stock withdrawn or transferred to the Southern Region.
