This locomotive was built in 1943 by the Hunslet Engine Company for the Ministry of Defence. It then entered service as WD 75030.
See LNER class J94 for details.
After serving with the Ministry of Defence the locomotive was sold to the National Coal Board (NCB).
It is recorded as being at the Central Workshop of the NCB at Allerton Bywater in March 1969, Newmarket Silkstone Colliery in October 1973 and Wheldale Colliery in 1982.
In 1982 Wheldale produced a record-breaking output of 500000 tonnes and in that year it was the last colliery in the UK to use a steam locomotive on its sidings. Wheldale closed in 1983.
The locomotive was based on the Caledonian Railway but its current home is unknown.
