R3991 BR, A3 Class, 4-6-2, 60103 'Flying Scotsman' (diecast footplate and flickering firebox) - Era 4

As the first steam locomotive to achieve an official 100mph run back in November 1934, this high-speed steam locomotive is instantly recognisable and has become an icon of British railway engineering. A1 Class 4472 'Flying Scotsman' entered traffic on the 24th of February 1923, unnamed, as LNER No. 1472. Selected as the LNER's prestige exhibit for the forthcoming British Empire Exhibition at Wembley, 1472 emerged from Doncaster Works on the 2nd of March 1924 with the Company's Coat-of-Arms adorning the cabside, a new number; 4472 and named as 'Flying Scotsman'.

On the 1st of May 1928, and fitted with a corridor tender, 'Flying Scotsman' undertook the first non-stop run from London to Edinburgh. In 1946 'Flying Scotsman' was rebuilt to A3 class specification and emerged in January 1947 having been renumbered by LNER as No. 103. In December 1948 'Flying Scotsman' was once again renumbered as a result of the nationalisation of the railways, becoming No. 60103. BR Painted the locomotive in a stunning BR Express Blue livery which was retained until 1954.
