NER Class P2 [LNER J26]

The NER Class P2, designated LNER J26 after the 1923 Grouping, was a series of inside-cylinder 0-6-0 goods tender locomotives designed by Wilson Worsdell and built at Darlington Works from 1904, representing the North Eastern Railway's standard heavy goods engine of the Edwardian era and one of the most numerous NER goods classes. The P2/J26 was built to work the intensive coal traffic of the Durham and Yorkshire coalfields, the ironstone and steel goods traffic of Teesside, and the general heavy freight that made the NER one of the busiest goods railways in Britain measured by tonne-miles of freight carried per route mile.

Wilson Worsdell had served as NER CME since 1890 and had developed a coherent programme of modern goods locomotive designs — the J21, J24, J25, and J26 classes forming a family of progressively improved NER standard goods 0-6-0s — each representing a development in boiler capacity, cylinder dimensions, or wheel diameter suited to slightly different traffic demands. The P2/J26 was the most numerous of these, built in substantial quantities at Darlington to provide the NER with reliable heavy goods capacity for the colliery-to-staithes coal runs, the iron ore trains to the Tees furnaces, and the general heavy goods working of the NER's busy freight network.

After the 1923 Grouping the LNER designated the P2 Class as J26 and continued the type in service on former-NER goods duties through the inter-war period. British Railways inherited the fleet in 1948 and continued operating them on North East England goods workings until progressive withdrawal in the 1950s and early 1960s. None of the J26 Class was preserved, though the closely related LNER J27 Class (Wilson Worsdell's 1906 development) is represented by No. 65894 at the North Yorkshire Moors Railway.
