NER Class P3

The North Eastern Railway Class P3, classified J27 by the London and North Eastern Railway, was a class of 0-6-0 steam freight locomotives designed by Wilson Worsdell as a relatively minor modification of the earlier Class P2. The main change was a deeper firebox with a shallower sloping grate, made possible by raising the boiler slightly and reducing the clearance between firebox and rear axle. Eighty were built between 1906 and 1909 in five batches shared among the railway's Darlington Works, the North British Locomotive Company, Beyer, Peacock and Company, and Robert Stephenson and Company. A further twenty-five with Schmidt superheaters followed in 1921 and 1922, and ten more were built in 1923. They hauled heavy mineral trains until the last was withdrawn in September 1967, and one, BR 65894, survives in preservation.
