File:LMS Royal Scot class 4-6-0 No46100 'Royal Scot' (27160672009).jpg

A Fowler design, seventy 'Royal Scot' class 4-6-0s were built as LMS express passenger locos between 1927 and 1930. They were all rebuilt to a Stanier design between 1943 and 1955 and the last was withdrawn in 1965. Only two now survive.

This most famous example was built at Derby Works in 1930 and was originally numbered 6152, with the name "The King's Dragoon Guardsman". In 1933 her identity was swapped with the original 6100 'Royal Scot' for the 'Century of Progress' international exposition in Chicago, IL. She then toured Canada and the United States and still carries a plate commemorating the event. In 1948 she became 46100 under British Railways and in 1950 she was rebuilt with a tapered boiler, becoming quite a different engine. Withdrawn in 1962, she was bought by Billy Butlin and painted in (somewhat inappropriately for a rebuilt engine) a crimson LMS livery. She then went on static display at the Ingoldmells Butlins site. In 1971 she moved to Bressingham Steam Museum near Diss and was back in steam by 1972, although by 1978 she was static again. I vaguely recall her giving footplate rides during this period, one of my earliest railway memories. She left Bressingham in 2009 and was eventually returned to mainline running condition, hauling her first tour in February 2016.

She is seen passing Foxcovert Road footbridge, just North of Peterborough on the route to Spalding. She is hauling "The Lindum Fayre" (train headcode 1Z46) an annual tour from Kings Cross to Lincoln for the Christmas market which she had taken over at Peterborough.
