The NER 1001 Class was a class of long-boiler 0-6-0 steam locomotive designed in Britain by William Bouch.
A total of 192 NER 1001 class locomotives were built from 1852 by a number of private manufacturers, as well as the NER's own works at Darlington and Shildon.
The last ten NER 1001s were delivered in 1875. Many were rebuilt in the following twenty-five years. The last was withdrawn in 1923. Having travelled an official mileage of 908,984 miles, locomotive number 1275 has been preserved.
