The NER Class S1 (LNER Class B14) was a class of 4-6-0 steam locomotives of the North Eastern Railway. It was designed by Wilson Worsdell and five locomotives were built between 1900 and 1901 at Gateshead works. The S1 was similar to the NER Class S but had larger driving wheels and a higher boiler pressure.

Modifications

Schmidt superheaters and longer smokeboxes were fitted between 1913 and 1917.

Use

When built, the S1s hauled heavy passenger expresses between York, Newcastle, and Edinburgh. Despite their generally high status, they proved to be insufficient with steaming and were seemingly no better than the S Class that came before them. As a result, they were gradually re-allocated onto goods traffic (mainly hauling fish trains) once the North Eastern's R and R1 4-4-0 classes entered regular service.
