The GWR 645 Class was a class of 0-6-0 saddle tank locomotives designed by George Armstrong and built at the Wolverhampton railway works of the Great Western Railway (GWR). Thirty-six 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 of the class, partially enlarged, were added in the 1501 numbering sequence. Unlike the originals, the "1501"s had full-length saddle tanks from the start. ==Construction== The whole class was delivered in nine lots, as follows: * 645-655, plus one (Lot O, 1872) * 656, 757-763, plus four (Lot P, 1872-3) * 764-775 (Lot Q, 1873) * 1501-1512 (Lot A2, 1878) * 1513-1524 (Lot B2, 1878-9) * 1525-1536 (Lot D2, 1879) * 1537-1548 (Lot E2, 1879-80) * 1549-60 (Lot F2, 1880) * 1801-1812 (Lot G2, 1881) Three of the un-numbered engines plus No. 767 were sold to the SWMR, and the other two plus No.655 to the C&CR. The latter three returned to the GWR in 1881, becoming Nos. 902-904. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「GWR 645 Class」の詳細全文を読む スポンサード リンク
