It has a guard's compartment in the centre and two large areas either side for storing luggage.

They were a very versatile type of coach and could be found all over the British Railways network and some are still in use today - although not in conventional use.

This was so the BG could go everywhere unlike their other Mark 1 counterparts which were banned from some station platforms because of their length.

Simultaneously, several BGs on have been converted for entirely different uses, due to the large space either side of the guard's compartment and the relative 'ease' of conversion.

Additionally, vehicle number 81432, previously based at Crewe, is to be converted into a bar/kitchen car by the Spa Valley Railway sometime during 2018.
