The Taff Vale Railway A class was a class of 0-6-2 steam tank locomotives designed by J. Cameron and introduced to the Taff Vale Railway in 1914. The A class was an enlarged version of the Taff Vale Railway O4 class designed by Tom Hurry Riches in 1907.

The A class locomotives were rebuilt with taper boilers and superheaters by the Great Western Railway (GWR) in 1924. All 58 passed to British Railways (BR) in 1948 but they were soon withdrawn and, by 1957, only no. 365 remained in service.

[edit] Builders and numbering

The locomotives were built in several batches by Hawthorn Leslie, Vulcan Foundry and North British Locomotive Company. Their GWR/BR numbers were in the range 303-440 but they were not consecutive and were intermingled with other classes.
