what is it?

The GWR 645 and 1501 Classes were two closely related classes of 0-6-0ST designed by George Armstrong and built at the Wolverhampton railway works of the Great Western Railway (GWR). Thirty-six, the 645 Class, were constructed between 1872-3, of which three were built for the South Wales Mineral Railway (SWMR), two for the Carmarthen and Cardigan Railway (C&CR) and the remainder for the GWR. In essence, they were saddle tank versions of his GWR 633 Class of 1871. From 1878, a further 72, the 1501 Class, partially enlarged, were added.
