The Taff Vale Railway O4 class was a class of 0-6-2 steam tank locomotives designed by Tom Hurry Riches and introduced to the Taff Vale Railway in 1907. They were rebuilt with taper boilers and superheaters by the Great Western Railway (GWR) from 1924.
[edit] Builders and numbering
The locomotives were built in several batches by Vulcan Foundry, Manning Wardle and Beyer Peacock. Their GWR numbers were in the range 200-420 but they were not consecutive and were intermingled with other classes.
