The B1 Class 4-6-0 locomotive was Edward Thompson's most enduring design. Built from 1942-1952, the class totalled 410 examples and was a familiar sight across former London & North Eastern Railway territory. Thompson's B1s presents many of the engines at work in the LNER and BR periods through 230 excellent colour and black and white images. The locomotives are pictured at locations such as: York, Newcastle, Darlington, Doncaster, Colchester, Grantham, King's Cross, Marylebone, Neasden, Nottingham, Edinburgh, Sheffield, Leicester, Hull, Fort William, Aberdeen, etc. The photographs, which have been taken at stations, sheds, lineside and workshops, are accompanied by well-researched and informative captions. Thompson's B1s celebrates the importance of the class in the history of the LNER and steam traction in Britain.
