The British Rail Class 315 is a fleet of alternating current (AC) electric multiple unit (EMU) trains, built by British Rail Engineering Limited at Holgate Road Carriage Works in York between 1980 and 1981; they replaced the Class 306 units. It was a variant of unit derived from British Rail's 1971 prototype suburban EMU design which, as the BREL 1972 family, eventually encompassed 755 vehicles across Classes 313, 314, 315, 507 and 508.[6] Revenue services with Class 315 units commenced in 1980 and continued until December 2022.[2][7]
