NER Class E1

The North Eastern Railway Class E1, classified as Class J72 by the London and North Eastern Railway, is a class of small 0-6-0T steam locomotives designed by Wilson Worsdell for shunting. They had inside cylinders and Stephenson valve gear, and were a development of the earlier NER Class E designed by his brother T. W. Worsdell, with smaller diameter wheels and larger cylinders. A total of 113 were built between 1898 and 1951, most of them at Darlington Works, with 25 built for the NER by Armstrong Whitworth and ten built by the LNER at Doncaster Works in 1925, which were originally given red lining. It is the only locomotive class built completely unchanged under pre-grouping, post-grouping and British Railways administration. Withdrawals ran from 1958 to 1964, and No. 69023 is preserved.
