context_page_description: The London Midland and Scottish Railway Coronation Class is a class of express passenger steam locomotives designed by William Stanier. They were an enlarged and improved version of his previous design, the LMS Princess Royal Class, and on test were the most powerful steam locomotives ever used in Britain at 2,511 dbhp. The locomotives were specifically designed for power as it was intended to use them on express services between London Euston and Glasgow Central; their duties were to include the hauling of a proposed non-stop express, subsequently named the Coronation Scot. The first ten locomotives of the Coronation class were built in a streamlined form in 1937 by the addition of a steel streamlined casing. Five of these ten were specifically set aside to pull the Coronation Scot. Although a later batch of five unstreamlined locomotives was produced in 1938, most of the ensuing Coronation class were outshopped as streamliners. Eventually, from 1944 to 1949, all new engines would be built in unstreamlined form and all the streamliners would have their casings removed. The very last of the 38 locomotives was completed in 1948.
context_section_description: The decision to adopt blue as the standard colour was subsequently reversed and Brunswick green was introduced in November 1951 with No. 46232 Duchess of Montrose. Between October 1955 and December 1957, all 38 locomotives carried it concurrently, the only livery the entire class carried.
  In the late 1950s the decision was made that the London Midland Region's main line locomotives could carry the colour maroon. This permission did not extend to the Scottish Region whose locomotives remained green until withdrawal.
  The LMR maroon was carried on 16 locomotives from the late 1950s: Nos. 46225-6, 46228-9, 46236, 46238, 46240, 46243-48, 46251, 46254 and 46256. No. 46245 was the first, in December 1957; a further fifteen examples followed between May and November 1958. The style of lining varied: the first six repaints into maroon (including No. 46245) were lined out in the LMS style; the last ten received the BR style of lining as used on the standard green livery; No. 46247, originally lined in the LMS style, was given the BR style in July 1959; and by November 1961 those with the BR lining were repainted to match No. 46245.
  Because of insufficient clearance between the locomotives and the 25 kV overhead electric wires south of Crewe, the whole class was banned from operating under them with effect from 1 September 1964. To highlight this prohibition a yellow diagonal stripe was painted on the cab sides. This inability of the locomotives to operate on the line for which they were designed was crucial in the decision to withdraw the entire class.
