In November 2014, Vivarail bought 156 driving motor cars and 70 carriages of ex London Underground D78 Stock which were being replaced by S Stock. The stated purpose of the Class 230 is to ameliorate a perceived shortage of affordable, modern rolling stock on Britain's regional rail routes, resulting from the slow pace of electrification.Electric units
Other units will retain their electric capability as they are re-engineered into Class 484 units for use on the Island Line.
