This locomotive was built in 1943, to a Hunslet Engine Company design, by Robert Stephenson & Hawthorn for the Ministry of Defence. It then entered service as WD75061.
See LNER class J94 for details.
After the end of the Second World War the locomotive was one of many that were acquired by the National Coal Board (NCB). In 1950 this colliery was employing nearly 3,000 workers.
It was used by the NCB at Eccles Colliery at Backworth in Northumberland which at 1,440 feet deep was the deepest in the Northumberland Coalfield. Here the locomotive ran as No 9. It was one of the last to operate steam locomotives but this locomotive along with the others still operating there were withdrawn from service in 1976.
In preservation the locomotive has been based on the Strathspey Railway. It last ran there until the late 2000s when it was taken out of service following the expiry of the boiler certificate. It is currently stored at Boat of Garten awaiting overhaul.
