GWR 56 Classとは 意味・読み方・使い方

The 56 Class were 2-4-0 tender locomotives designed for the Great Western Railway by Joseph Armstrong and built at Swindon Works in 1871-2. 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 6' in diameter.
