This Graham Farish Class 31/1 sports all the hallmarks of a refurbished machine with its bufferbeam cowling and bodyside band removed, headcode boxes plated over and radio pods present above each cab. The attractive BR Railfreight livery is faithfully applied and, being a coal sector loco, it may come as a surprise to learn that the locomotive was actually named after a nuclear power plant, for the coal sector was also responsible for resourcing nuclear traffic and No. 31130 is named after the Calder Hall plant in Cumbria.
