GWR 806 Classとは 意味・読み方・使い方

The 806 Class (20 locomotives, nos. 806-825) was Joseph Armstrong's last design of 2-4-0 mixed-traffic locomotives for the Great Western Railway, built at Swindon Works in 1873. A further 20 locomotives were added by Armstrong's successor William Dean in 1881-2; numbered 2201-2220, these had modern domeless boilers. The class had a similar appearance to the 717 Class but had driving wheels 6" larger. Most of the Armstrong locomotives worked in the Southern Division, and carried Sir Daniel Class boilers; only Nos. 806, 807, 810 and 821 were Northern Division engines, and these were in due course fitted with Wolverhampton boilers.
