type. This was because the nature of the work they undertook demanded high adhesive weight, plenty of power with good braking ability, but no need for outright speed, nor large tanks or bunker as the distances from pit to port were short. These Welsh locomotives were taken over by the GWR at the grouping in 1923 and many were rebuilt with GWR

Rhymney Railway

The Rhymney Railway's A, M and R classes were successful designs ideally suited to hauling heavy coal trains a relatively short distance. In 1926, No 17 was reboilered by the GWR and in this form was visually almost indistinguishable from the

. These three classes (and the larger wheeled P class) were designed for work on the Rhymney Railway, replacing smaller locomotives. When the smaller railway companies were forcibly merged into the GWR in 1923, these modern 0-6-2Ts were in generally good order (some were a few months old) and had proved successful. Collectively they became the blueprint for the 200 strong GWR 5600 class. The design of the 5600 followed the Rhymney designs quite closely but adopted GWR practice as far as possible, by utilising many

Some A and P classes were also rebuilt but used the slightly shorter standard number 10 boiler, also to good effect. Five R class locos were upgraded from 1926 onwards. All told sixteen "Stephenson" locos were similarly dealt with between 1926 and 1949.
