[2] In the 1970s, it was based on the Keighley and Worth Valley Railway (KWVR) during the main line steam ban on BR (which was broken in 1971).

[3] 6115 was purchased by the West Coast Railways and in 2008, it was restored to main-line running standard at Carnforth MPD.

The loco was then repainted BR Brunswick Green, appearing in this livery at the Steamtown Open Weekend on 26/27 July 2008.

The loco then hauled its first railtour called The Settle-Carlisle Venturer from Hellifield to Carlisle and returned on 16 August 2008.

On 6 September 2009, 46115 worked "The Yorkshire Scot" from Liverpool Lime Street to York running via Manchester Victoria, Rochdale and Leeds.

On 26 July 2016, 46115 made its first appearance on the Conwy Valley line when she worked RTC's Welsh Mountaineer from Preston to Blaenau Ffestiniog running via Chester and Llandudno Junction.

[4] This was also the first time a Royal Scot had ever gone up the branch, as none of the class ran up the line in the steam era due to the fierce 1 in 47 gradient in the Blaenau direction being unsuitable for an express passenger locomotive.

In 2018 a new inside cylinder was cast for the locomotive and 46115 returned to the main line in late July 2019 with a 'light engine' test run.

On 8 September 2019 it worked from Hellifield to Carlisle in a final unannounced 'proving run' (also its first public passenger special since overhaul), when it piloted to Merchant Navy 35018 British India Line, which had brought the West Coast Railway-promoted train from York.
