Class Details by Steve Llanso of Sweat House Media

Class 24 (Locobase 16105)

Data from drawing archived at [], last accessed 26 July 2015. Works numbers were 342-345 in 1854.

A note in the archives directory says that these engines were completed in 1854, but not paid for until 1857.

Class 5 (Locobase 10198)

Data from "An Early Shrewsbury and Chester Engine", The Locomotive Magazine, Vol VI (August 1901), p. 137..

The photograph illustrating this early passenger engine gives Locobase the impression of a clumsily built model of a "typical" engine. It's probably the large hubs on the drivers and the latter's spindly spokes, a very large leading wheel with spokes resembling those of a wagon wheel, the bare splashers over the upper segment of each driver, and the 4-cornered haystack boiler.

Essentially a Longboiler with an uncoupled front axle, this engine passed into Great Western hands in 1854. In 1865, the engine led a double-headed train and ran off the rails at Rednal. The driver and several passengers were killed. The locomotive was scrapped three years later.
