British Rail Class 312
The English used in this article may not be easy for everybody to understand. (March 2012)
The British Rail Class 312 is a type of alternating current (AC) electric multiple unit (EMU) built in 1966-1974 intended for use on outer-suburban passenger services. It was the last class of multiple unit to be constructed to the British Rail Mark 2 bodyshell, and also the last with slam doors. This latter feature contributed to their relatively early withdrawal (between 25–28 years old, compared to a life expectancy of 30 years). Ironically, the examples withdrawn by First Great Eastern and later 'one' Great Eastern between 2003 and 2004 were slightly newer than most of the carriages the operator is introducing during 2005 for use on its premier express service.
