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.^[1]

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. They were gradually replaced on these services by NER Class R and NER Class R1 4-4-0s. From 1907, they were mainly used for hauling fish trains.
