BR standard class 5
From Wikipedia, the free encyclopedia
The British Railways Standard Class 5MT 4-6-0 was one of the standard classes of steam locomotives built by British Railways in the 1950s. 172 were built, essentially being a development of the LMS black five.

[edit] Background
William Stanier's black five had been the most successful mixed-traffic types in Great Britain. Construction of the black fives had started in 1934 and continued past nationalisation to 1951. A new set of standard locomotives was to be built by British Railways, based on LMS designs and incoporating modern ideas.
[edit] Design and construction
The design work was done at ex-LNER works at Doncaster but the bulk of the construction was done at Derby. The locomotive featured a Type 3B boiler almost identical to the black fives'. A higher running plate and slightly enlarged driving wheels from 6' to 6' 2" and a standard cab were the most obvious visible changes.
The first of the class, 73100 was outshopped from Derby in April 1951 and 30 were in service by January 1952. There was then a gap in construction before Derby resumed building its remaining 100 engines. 42 were built at Doncaster, starting in August 1955 and finishing in May 1957 with Derby's last engine following a month later.
30 engines, numbers 73125 to 73154 were built with Caprotti valve gear.
