was moved by road to the Mid Hants Railway. It eventually undertook a proving run on Sun 26 Jun from Alton to Fratton before entering mainline service later in the year. 45231 returned to traffic in 2013 after another major overhaul was carried out at Carnforth MPD. In March 2015, 45231 paid a visit to the Llangollen Railway to attend the Steel Steam & Stars IV gala which was running over 2 weekends from Fri 6 to Sun 8 Mar & Fri 13 to Sun 15 March. Due to the railway not being connected to the national network, it had to be moved by road from Carnforth and the entrance to the yard at Llangollen was very tight. During the first weekend of the gala, the locomotive was failed with cylinder problems and was not able to take part in the remainder of the gala, with the engine returning to Carnforth shortly after the gala finished. The locomotive was, until May 2015, owned by Bert Hitchen and after his death, the locomotive was taken into the care of the Hitchen family who looked after the engine until November 2015, when Jeremy Hosking purchased the locomotive from the Hitchen family. 45231 is currently based at Crewe Diesel TMD alongside a number of other mainline certified locomotives to help with charter trains. Its current mainline certificate expires in 2020 with the boiler certificate running out in 2023. Fame in Preservation 45231 was used in the 40th anniversary special of the Fifteen Guinea Special on 10 August 2008. It worked alongside fellow class engine 45407 when they double headed the train from Carlisle back as far as Blackburn. 45231 then worked the train alone back to Liverpool Lime Street via Wigan. 2013 marked the 45th anniversary of the end of regular steam on British Railways in August 1968, and because 11 August was on a Sunday, it was fitting that the special was to run on the exact day 45 years after the 1968 run. 45231 was one of the chosen engines to work two special one-off railtours in August. The first trip was on Wednesday 7 August, working one of Statesman Rail's Fellsman trains which was renamed for the occasion "The Fifteen Guinea Fellsman", which also had the 1T57 headboard fitted alongside the regular Fellsman headboard. It ran in double-headed form with sister engine 44932 from Lancaster to Carlisle and back via
