Welsh 0-6-2T locomotives were a standard steam locomotive of the railways of South Wales. Many of the independent railways used them and, at the grouping of 1923, the survivors passed into Great Western Railway (GWR) stock. The GWR perpetuated the type in the GWR 5600 Class. The other major railway company in Wales, the LNWR, also had the LNWR Webb Coal Tank Class, though this was grouped into the LMS not the GWR.
