The British Rail Class 507 is a type of electric multiple unit (EMU) passenger train built by British Rail Engineering Limited at Holgate Road carriage works in two batches from 1978 to 1980. They are a variant of British Rail's standard 1972 design for suburban EMUs derived from PEP stock, which eventually encompassed 755 vehicles over five classes (313, 314, 315, 507 and 508).[6] They have worked on the Merseyrail network from new until their retirement in November 2024. Between 2002 and 2005, all units were refurbished by Alstom's Eastleigh Works.

The remaining class 507 units are all now at least 44 years old, and, following the withdrawal of the Class 313 fleet in 2023, were the oldest units operating on the mainline rail network in Great Britain.[7] However, the even older 1972 Stock and 1973 Stock are still in service on London Underground's Bakerloo and Piccadilly lines.

A final farewell tour took place on 3 November 2024.[1]
