British Rail Mark 3 : ウィキペディア英語版 | British Rail Mark 3
British Rail's third design of standard passenger carriage, designated the Mark 3, was 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 2015. ==Introduction==
Under the chairmanship of Stanley Raymond, it was decided to reduce journey times further on long-distance trains by increasing line speed to 125 mph where practical - the maximum considered possible on Britain's Victorian-age railway. At the end of 1968 proposals were submitted to the Commercial and Operating Departments of British Rail for a new fleet of third-generation standard coaching stock, designed to run at 125 mph. The rapid development required for the HST in 1969 made the Mark 3 coach design the obvious choice for this train, and in 1972 the first Mark 3 coaches were built, ten for the prototype HST.
