GWR 56 Class
The GWR 56 Class were tender locomotives designed for the Great Western Railway by Joseph Armstrong and built at Swindon Works in 1871-2. Design and construction. There were 11 engines in the class, of which the prototype, No. 56 itself, was built in 1871; the remaining ten were numbered 717-726 and appeared the following year. They were larger and longer than Armstrong's 439 and 481 classes, and the original boilers were of the type used for his goods engines. The driving wheels were in diameter. Use. Ahrons states that Nos. 56, 717, 719, 720  and 724 were allocated for 20 years to Weymouth, and that the rest were at Bordesley for even longer, hauling trains to Chester and Hereford. All ran more than a million miles, and they disappeared between 1903 and 1919. Accident. On 12 November 1894, locomotive No. 720 was hauling a boat train that was derailed at Yetminster, Dorset due to flood damaged track.
