GWR 94XX CLASS LOCOMOTIVE

BRIEF HISTORICAL DETAILS

This class of engines were designed and built to answer a request from the traffic department for more 8750 engines. Allegedly the Board wanted a more modern looking engine so Hawksworth set to and designed and built the last GWR engine, the later 1500 Class were BR built. Large numbers of the engines were built by sub-contractors and some of these engines had boilers supplied by Swindon. Not all the design changes were successful. The wider cab made it harder for the driver to reach the brake handle while shunting and the change from coil springs on the rear axle to underhung leaf springs made the ride more lively. The engines were built as follows:  

VARIATIONS POSSIBLE WITH THE KIT

A photograph of your chosen locomotive is recommended when sorting these variations.

Rivets  The locomotives built by R Stephenson have a different pattern of rivets on the two horizontal rows at the base of the bunker. Some Yorkshire Engine Co. locomotives are the same.
Some engines (9410 & 9411) appear to have no lines of rivets on the cab and bunker.
Cylinder Sloping Front Cover  Locomotives appeared with and without this cover.
Rear Buffer Beam Footstep  The lower footsteps for the bunker were either attached to the rear of the hanging plate or to the rear buffer beam. Some locomotives had the footsteps removed.
