Brecon and Merthyr 0-6-2T locomotives

The Brecon and Merthyr 0-6-2T locomotives were steam tank locomotives of the Brecon and Merthyr Railway, comprising the class 36 and the class 45. The class 36 was introduced into traffic in 1909 from a design by the Rhymney Railway's engineer Hurry Riches, with four locomotives at first and eight by 1914. They were built by Robert Stephenson and Company and were almost identical to the Rhymney Railway R class apart from a round-topped boiler. The railway also borrowed from the Rhymney Railway P class for six more engines, loosely known as the 45 class. They were substantial tank engines of about 66 tons, rebuilt by the Great Western Railway with its own boilers, with the first withdrawal in 1947 and the last in 1954.
