Engine Shed 200 Metres West Of Campbell Drive (In Unnamed Road)

The engine shed, located 200 metres west of Campbell Drive, is a locomotive roundhouse built around the 1870s for the Staveley Coal and Iron Company. It features an iron frame clad in brick, with a part-glazed roof that has been renewed (originally it was covered with lead sheeting) over the roundhouse, while the ancillary buildings have a Welsh slate roof. The building's plan remains completely intact.

The roundhouse, which is rectangular in shape, houses a turntable with 22 tracks, nine of which have service pits. In the southern and western corners, there are the fitters' workshop and office. The eastern corner contains the general office, while the northern corner features a sand-dryer situated in a tower above a kiln. The western corner has a water tank above a general workshop. Detached to the southwest are the mess and lamp shed, the machine shop, and a later sander unit at the entrance, likely added in the 1940s, to help locomotives grip the rails.

All ancillary buildings are constructed of brick with simple detailing, including windows under cambered arches, some of which retain their original small-pane frames, except for the timber lamp shed. The machine shop is notable for its prominent louvred roof. The principal roundhouse has H-section iron or steel uprights, with valley gutters that lead into attached downpipes. It features six by five unequal bays and a cobbled floor, along with extractor fan fittings (the fans have been removed). The turntable was renewed around 1931 by Cowans, Sheldon & Co Ltd from Carlisle. This building served as both a workshop and a turning place for locomotives operating in the local coal mines and iron works. As of 1990, it is the last operational roundhouse in Britain and is significant for retaining all of its associated buildings.
