A British Rail 6 Wheel Coach converted and used as a power source, a Generator Coach is an innovative and curious device serving in a capacity far different from the typical expectation of a coach simply to carry. 
In lines where a pantograph was not freely available to power electric trains, a power outage appears unexpectedly or even a hotel or other building required electricity; the Generator Coach was an emergency tool at hand.
