Following a return to service on 11 August 1998, the engine was main line registered, and did haul several main line steam specials on the national rail network, but after failing twice on a railtour to Stranraer in May 2000, the engine was confined to heritage rail operation only. It was hoped to have run 45110 on the 2008 recreation of the "Fifteen Guinea Special", but this was not possible as the engine was due to come out of ticket on 11 August, the same day as the "Fifteen Guinea Special" re-run, and so a competition was offered by "Steam Railway" magazine to drive the engine on 11 August. Despite this, the engine was given an extension to its 10-year boiler ticket up to the end of August, at the end of which, the loco was withdrawn after 10 years of service.
