History

The Class 315 electric multiple units were built by British Rail Engineering Limited’s York works from 1980 to 1981. They were the fifth and final variant of British Rail’s then-standard 1972 design for suburban EMUs. They are only able to operate from the 25 kV overhead line and were built to replace the life expired class 306 electric multiple units operating at the time.

With their 75mph maximum speed and seating capacity of 318 for each 4-car set, the units proved ideal for metro style working on London suburban lines and have operated for 37 years so far in that role.

The units currently employed by London Overground were inherited from Abellio Greater Anglia as part of the takeover of the Lea Valley/Romford to Upmister lines in 2015.  The units are leased to London Overground by Eversholt Leasing.

In July 2015, Transport for London confirmed that it would place a £260m order for 45 Bombardier Aventra Class 710 electric multiple units to replace London Overground’s 315s on the London Liverpool Street – Cheshunt/Chingford/Enfield Town lines.
