100 years ago -March 1918

ROBINSON GCR 1169

LORD FARRINGDON 4-6-0

Back in the day, Model Engineer published excellent contemporaneous articles on new steam locomotives by  Chas S Lake. A hundred years ago it was the latest Robinson design for the Great Central Railway, the class 9P (later LNER B3). This was Robinson’s largest passenger locomotive design. The first locomotive was built at the end of 1917 and named after the GCR chairman, Lord Farringdon. It is said to have been inspired by the London & North Western Railway's (LNWR) Claughton class.

Unusually, the B3s had Stephenson valve gear. Cranks for the inside cylinders were 180 degrees apart from their adjacent outside cylinders. Each outside cylinder was driven by the same set of valve gear as the adjacent inside cylinder, using a rocking motion and different admission arrangements for the cylinders. The outside cylinders had outside admission, and the inside cylinders had inside admission. The inside cylinders had cranks 90 degrees apart.

The inside cylinders drove the front axle, the outside cylinders drove the second axle. The B3s had a similar boiler to the Sir Sam Fey B2 class, and had a similar general appearance.

None survived into preservation.

Nearest live steam model design of these attractive Robinson engines is Don Young’s two cylinder Immingham 4-6-0.
