The **NER Class S1** ([LNER](/source/London_and_North_Eastern_Railway) Class B14) was a class of [4-6-0](/source/4-6-0) [steam locomotives](/source/Steam_locomotive) of the [North Eastern Railway](/source/North_Eastern_Railway_(United_Kingdom)). It was designed by [Wilson Worsdell](/source/Wilson_Worsdell) and five locomotives were built between 1900 and 1901 at [Gateshead works](/source/Gateshead_works). The S1 was similar to the [NER Class S](/source/NER_Class_S) but had larger driving wheels and a higher boiler pressure.[1]

## Modifications

Schmidt [superheaters](/source/Superheater) and longer [smokeboxes](/source/Smokebox) 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](/source/NER_Class_R) and [R1](/source/NER_Class_R1) [4-4-0](/source/4-4-0) classes entered regular service.

All five locomotives were withdrawn between 1929 and 1931 and none were preserved.
