The new Royal Scot was sent to the Century of Progress Exposition of 1933 and toured Canada and the United States with a train of typical LMS carriages.

[4] Following the tour, special commemorative plates were fitted below the nameplates which read:[5][6] 6100 was renumbered 46100 by British Railways after nationalisation in 1948.

46100 was bought by Billy Butlin of Butlins holiday camps after withdrawal and after cosmetic restoration into LMS crimson lake at Crewe Works, although this was the original livery received, the locomotive did not carry it after being rebuilt (only one rebuilt Royal Scot ever carried LMS crimson lake livery and that was 6170 British Legion).

After sale to the Royal Scot Locomotive and General Trust (RSL>) in April 2009, it was moved by road to Pete Waterman's LNWR Heritage workshops in Crewe.

[8] On 20 March 2009, Royal Scot caught fire en route to a steam gala at the West Somerset Railway.

[citation needed] It performed its light and loaded test runs on Tuesday 22 & Wednesday 23 December 2015 and worked its debut railtour on Saturday 6 February 2016.
