s, designed by
John G. Robinson in 1918. They were a
mixed traffic class. All three examples were withdrawn in November and December 1947.
Design
The first member of the class (No. 416) was built 1918, in the middle of a batch of
GCR Class 8A 2-8-0
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles, and no trailing wheels. ...
locomotives and the design had an identical boiler, cylinders and motion to this class. For three years this remained the only example of the class, but in 1921 Robinson built two further examples, with the intention of comparing their performance with his four-cylinder
GCR Class 9P design and later decided to produce more of the 9Ps.
The 8N was intended as an improved version of the
1A (LNER B8 class) of 1913, which had large inside cylinders and relatively small axleboxes on the driving axles. Although 8N was an improvement of the 1A design, .The 9P design of 1917 had four cylinders, resulting in a more balanced locomotive with smaller cylinders.
Allocation and work
Although very competent locomotives, the three examples of this class were non-standard and used on a variety of secondary freight and passenger duties over the former Great Central Railway system. They were eventually replaced in 1947 by members of the
B1 class. No examples survived.
