Neath and Brecon Stephensons

The Neath and Brecon Stephensons were three 0-6-2T tank locomotives introduced on the Neath and Brecon Railway in 1904 from a Rhymney Railway design. They were built by Robert Stephenson and Company and were almost identical to the successful Rhymney Railway M class, whose design the Brecon and Merthyr Railway also used as a blueprint for its own 0-6-2T locomotives built from 1909 to the pattern of the Rhymney R class. In 1922 the three Neath and Brecon engines were repaired by the Great Western Railway, which took them over, and they lasted until 1929 to 1930. Unlike many other South Wales 0-6-2T engines of this kind, they were not rebuilt with Great Western taper boilers.
