The Great Central Railway Class 9Q, classified B7 by the LNER, was a class of 4-6-0 mixed traffic locomotives designed by John G. Robinson for fast goods, relief passenger and excursion services. They were a smaller wheeled version of Robinson’s earlier Lord Faringdon express passenger class (LNER Class B3).
The GCR built two batches at Gorton locomotive works, during 1921 and 1922, and they also ordered batches from Vulcan Foundry and the Beyer, Peacock and Company. Twenty eight locomotives had been delivered by Grouping in 1923. The London and North Eastern Railway (LNER) ordered a fifth batch of ten locomotives from Gorton works and these were delivered between August 1923 and March 1924.[1] The last batch had reduced boiler mountings and detail differences to the cab to conform to the new LNER loading gauge. These were classified B7/2. The earlier batches were classified B7/1. Thirty-eight locomotives passed to British Railways in 1948, but withdrawal began soon afterwards. None have been preserved.
Some locomotives surviving in 1949 were renumbered between 61702 and 61713.
