The British Rail Mark 3 is a type of passenger carriage developed in response to growing competition from airlines and the car in the 1970s. A variant of the Mark 3 became the rolling stock for the High Speed Train (HST).

The InterCity 125 or High Speed Train (HST) is a diesel-powered high-speed passenger train built by British Rail Engineering Limited between 1975 and 1982. A total of 95 sets were produced, each comprising two Class 43 power cars, one at each end, and a rake of seven or eight Mark 3 coaches. The name is derived from its top operational speed of 125 mph (201 km/h). At times, the sets have been classified as British Rail Classes 253, 254 and 255.
