GWR 1813 Class
The Great Western Railway's 1813 Class was a series of 40 0-6-0 side-tank engines built at Swindon Works in two lots of 20 engines each:
- Nos. 1813-1832 (Lot 59, 1882-3)
- Nos. 1834-1853 (Lot 60, 1883-4)
This was the first 0-6-0 tank design of William Dean and in its concept and dimensions may be regarded as the precursor of all the larger GWR pannier tanks of the 20th century, such as the 5700 and 9400 classes:
- Inside frames
- Wheels 4 ft 6 in (1.37 m) diameter, wheelbase 15 ft 6 in (4.72 m)
- Cylinders 17 in × 24 in (430 mm × 610 mm)
From 1894 some of the 1813s were rebuilt with saddle tanks, and in 1903-6 six were rebuilt with either short or full-length pannier tanks, resulting in a very early example of this type of engine. The rest were so converted between 1911 and 1925, as had become standard practice on the Great Western. The class also carried an unusually wide variety of different boilers. Nearly all of these engines spent their lives on the GWR's Southern Division. No. 1835 alone passed into British Railways stock, to be withdrawn in January 1949.
