This locomotive is an Austerity type locomotive built for the Second World War effort by W G Bagnall in 1944. Bagnall built the locomotive as a sub-contractor to Hunslet Engine Co Ltd. Bagnall built 52 of the 377 that were built for the War Department between 1943 and 1947. This locomotive carried the number WD 75158. The LNER bought some of these locomotives which became the J94 class.
At some time it was sold by the War Department to the National Coal Board (NCB). The NCB bought a number of these locomotives from the War Department as well as buying 77 as new between 1943 and 1964.
The locomotive ended its working life with the NCB at Featherstone Colliery and was purchased in 1983 by a group of Peak Rail members. It was then moved to Pak Rail at Buxton where it was restored and gainedthe name The Duke. The restoration of the locomotive was aided financial by the West Derbyshire Council and was completed in 1988.
It then moved to the Peak Rail Darley Dale site in 1990 and was used on train services.
During preservation it has carried a British Rail livery and number 68012 masquerading as a Class J94. The real 68012 was built by Hunslet Engine Co Ltd and spent some of its life on the Cromford and High Peak Railway in BR days. Bagnall works no 2746 was never owned by British Rail.
The locomotive moved to the Ecclesbourne Valley Railway in November 2010 and is currently under restoration. Having run for several years on Peak Rail it required further routine boiler work. The 48624 Society (8F Group) are helping to complete this work.
By March 2018 reassembly of the connecting rods and motion was complete and the steam-heating and vacuum pipes had also been refitted. A new bunker had also been fitted. The bunker was fabricated by Locomotive Maintenance Services of Loughborough who were also undertaking the overhaul of the boiler.
