summer 2018. No.401 No. 401 was one of a class of three built for the Steel Company of Wales in 1950, as works number 2994 (2995 and 2996 were built in 1951), to an advanced specification designed to provide a low maintenance competitor to the diesel shunters emerging. As such it had many advanced features not seen on other industrial steam locomotives. It was sold to Austin Motor Co. Ltd., of Longbridge, Birmingham in 1957 before passing in 1973 to the developing West Somerset Railway. Once it became surplus to larger locomotives there, the Stephenson Railway Museum purchased 2994 and repainted it from "Kermit the frog" green to a black livery similar to a NER style. The locomotive was placed on static display in 2008. After a 6 year restoration period it returned to active service in Easter 2019. In 2020, 401 was repainted into its original 'Steel Company of Wales Ltd' unlined maroon with lemon lettering livery. No.69 No.69 was built in 1953, works number 3785. The engine spent its entire working life at South Hetton Colliery which served the Hawthorn and Murton colliery complex as well as Seaham. In preservation, it ran at the Yorkshire Dales Railway, now the Embsay and Bolton Abbey Steam Railway, from 1977 until 1984 before being parked up pending overhaul. Restoration is planned to begin in the winter season pending other commitments on site. No.69 is privately owned by an NTSRA member/volunteer. Diesel locomotives No.08915 No.08915 (originally D4145) used to be of Allerton (AN) depot. Restored to BR Blue in 2017. No.03078 No.03078 (originally D2078) used to be of Gateshead (GD) depot. Repainted into BR Blue early 2019. No.10 An early diesel built in 1958, Consett Iron and Steelworks No.10 is the last example of in-house production of locomotives by industrial railways in the North East. It was conceived in their Templetown workshops to satisfy a need for a 300 hp shunter with mechanical transmission, and was based on a Hunslet design. It was built by reusing many parts from steam locomotives. Eventually redundant to Sentinel's with hydraulic transmission, it was donated in 1976 to the Tyne and wear Museums Service by the work's later owner, the British Steel Corporation. No.10 is currently not operational, requiring a new set of batteries and rewiring before operating again. Electric locomotives Harton Electric E4 Electric locomotive No.E4 was built for the Harton coal system at South
