Passenger Car, British Rail, Mark 3 Coach

History: The British Rail Mark 3 is a type of passenger carriage developed in response to growing competition from airlines and the car in the 1960s. A variant of the Mark 3 became the rolling stock for the High Speed Train (HST).
Originally conceived as locomotive-hauled coaching stock, the first coaches built were for the prototype HST in 1972. Production coaches entered service between 1975 and 1988, and multiple-unit designs based on the Mark 3 bodyshell continued to be built until the early 1990s. The Mark 3 and its derivatives are widely recognised as a safe and reliable design, and most of the surviving fleet is still in revenue service on the British railway network in 2018.
The Mk 3 coaches have been painted in a large variety of liveries since privatisation. A total of 848 have been produced in various types: First, Second, Second with Guard compartment (TGS), Buffet (TRSB), Restaurant (RFM), Sleeper (SLE).

From Wikipedia

Railroad/Company: British Railways (BR), which from 1965 traded as British Rail, was the state-owned company that operated most of the overground rail transport in Great Britain between 1948 and 1997. It was formed from the nationalisation of the "Big Four" British railway companies and lasted until the gradual privatisation of British Rail, in stages between 1994 and 1997. Originally a trading brand of the Railway Executive of the British Transport Commission, it became an independent statutory corporation in 1962 designated as the British Railways Board.

British Rail designed and manufactured rolling stock from 1948 to 1989, at which time its subsidiary British Rail Engineering Limited (BREL) was privatised.

1997 marked the end of the privatization effort in which the last assets of British Rail were sold to 31 regional freight and passenger operators as well as Railtrack (which was later brought under public control as Network Rail), which was given the track and infrastructure.
