Manchester Pullman Mark 3 carriages were used on the Manchester Pullman from May 1985, with a batch of Mark 3b carriages being built at Derby as Intercity Pullman cars, some named.

Entertainment carriages In 2009 First Great Western introduced 'entertainment carriages' with at-seat television screens known as Volo TV. The system, which FGW claimed was a "world first", was fitted to Coach D in Standard Class.

In addition to radio and video feeds, a GPS train-location screen allowed passengers to check and track train progress. For this purpose an aerial had been fitted to the roof of these coaches.
