The British Rail Class 312 is a type of alternating current (AC) electric multiple unit (EMU) built in 1975-1978 for use on outer-suburban passenger services. It was the last class of multiple unit to be constructed with the British Rail Mark 2 bodyshell as well as the last with slam doors in Britain. These features contributed to their relatively early withdrawal at 25–28 years old compared with a typical EMU life expectancy of 30–40 years.
