Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Great Central Railway Class 9N, classified A5 by the LNER, was a class of 4-6-2 tank locomotives designed by John G. Robinson for suburban passenger services. They were fitted with superheaters, piston valves and Stephenson valve gear. The GCR built three batches between 1911 and 1917. They ordered a fourth batch but this was not built until after Grouping in 1923. The London and North Eastern Railway ordered a fifth batch from Hawthorn Leslie and Company and this was built between 1925 and 1926. The last batch had reduced boiler mountings and detail differences, and was classified A5/2. The earlier batches were then re-classified A5/1.
