This locomotive was built by Robert Stephenson & Hawthorn in 1951. Originally it was intended to work at Bolton power station but after a couple of years at the on loan to the Chadderton power station it moved to Agecroft in 1954. At Agecroft Colliery it became Agecroft No 3.
In 1957 the power station passed into the ownership of the Central Electricity Generating Board (CEGB).
The engines became redundant when a conveyor belt was constructed to bring the coal supplies in directly from Agecroft colliery. Its last day of operation at Agecroft was in September 1981.
The locomotive was initially preserved at the Museum of Science and Industry in Manchester but was disposed of from there in 2000 when it moved to Long Marston in Warwickshire. It later moved to Swindon where it spent many years on static display at the Museum of the Great Western Railway.
The locomotive was later purchased by the Whitwell & Reepham Railway where it is being restored.
