The class was introduced in 1914 as a rebuild of Wilson Worsdell's NER Class W 4-6-0T (introduced 1907). On being acquired by the London and North Eastern Railway in 1923 the W1s were re-classified A6. The information in the infobox (right) is taken from sources.[1][2]

Modifications
Seven of the locomotives were fitted with superheaters between 1937 and 1944.[3]
British Railways
One locomotive was withdrawn in 1947 but the remaining nine passed to British Railways in 1948 and were numbered as follows:
- Superheated: 69791-69793 and 69796-69797
- Non-superheated: 69794-69795 and 69798-69799
This seems to conflict with the claim that seven locomotives were fitted with superheaters but, possibly, the superheater was removed from one locomotive. This might have happened when a boiler was changed.
Withdrawal
One locomotive was withdrawn in 1947 and the others had all been withdrawn by the end of 1951. None is preserved.
