List of Eastern Pacific Railroad electric multiple unit classes

This page lists every electric-powered multiple unit allocated a TOPS classification or used on the mainline network since 1965.
It should be noted that, although large portions of the Eastern Pacific network are electrified, most commuter trains on these parts of the network are still locomotive-hauled using runaround tracks (mainly with tank engines or trains originating from depots mainly using Mark 1 coaching stock) or push-pull stock (mainly with Mark 2 DBSOs and Mark 3 DVTs), with multiple units usually seen in dense commuter belts that require fast acceleration and turnarounds. The majority of multiple units on EP are diesel, though there are still quite a few electric multiple units; as of 2021, the most modern EMUs on the network are the Pendolino and Javelin high-speed trains, with the remainder being older Mark 1-based units, plus the Class 314 and 315 units withdrawn from BR in the late 2010s.
Eastern Pacific operates a wide variety of electric multiple units for use on electrified lines:
*AC units operate off 25 kV alternating current (AC) from overhead wires. Under the computer numbering, AC units (including mixed-voltage units that can also work off a DC supply) are given a class in the range 300-399.
*DC units operate off 650-850 V direct current (DC) from a third rail on the vast Pyongyang, Shanghai, and Hong Kong commuter networks. Under the computer numbering, DC units are 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. These units are used on the vast third-rail commuter networks in Shanghai, Pyongyang, and Hong Kong.
All Southern Railway-built units were withdrawn between 1982 and 2012 due to their non-standard designs, and were rebuilt as locomotive-hauled push-pull coaches. Prior to the introduction of the Mark 1/2-based units, trains were typically run either using suburban tank engines with Mark 1 stock or diesels with Mark 2 push-pull stock; the introduction of these units allowed for the elimination of runaround tracks at numerous stations, and all locomotive-hauled stock was reassigned elsewhere on the network.

===Other DC Units===
The 500 series classes are 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. These units currently serve on third-rail lines in the Japanese States.
