TheGreat Eastern Railway (GER) Class G14 was a class of2-4-0steam locomotives.
The Class G14 was designed byThomas William Worsdell for the express service fromLondon toNorwich, the first locomotive produced while he was superintendent. A total of 20 were built, 562–564 in late 1882 and the rest in 1883.
The locomotive was designed for the Great Eastern Railway's London to Norwich route on which the frequent sharp curves between London and Cambridge necessitated that the wheelbase not be entirely rigid, so a radial axle box was fitted to the front wheels giving 1.5 in (3.8 cm) of side motion each way controlled by a horizontal elliptical spring. It usedJoy valve gear, with the valves placed on top of the cylinders, allowing them to be brought closer together allowing larger cylinders and longer bearings, the Joy valve motion having the benefit of not requiring space on the crankshaft for eccentrics.[1]
The locomotives were numbered 562 to 571, and 640 to 649, 20 in total.[2]
