7063 was built in 1942 at the Forth Bank Works in Newcastle for working at Dunston Power Station in Gateshead.
It worked at Gateshead shunting coal waggons until it was saved for preservation by the Hexham Rolling Stock Group (now disbanded) and taken into the National Collection in 1978.
It then ran in its CEGB green livery and acted as Percy in National Railway Museum Thomas the Tank Engine events.
Its boiler certificate expired in 2009 and in was planned to undertake a heavy overhaul of the locomotive so that it could be operational again. At that time it was thought that the engine was in good condition but in early 2014 these plans were changed as the cost of returning it to traffic had increased to an extent that it was considered too high.
As 7063 was a duplicate of locomotive Agecroft 1 which was also part of the National Collection it was gifted to the Foxfield Railway in 2014.
At the end of 2018 the locomotive was used for steam heating duties at Pickering on the North Yorkshire Moors Railway.
