    The London and North Eastern Railway (LNER) Thompson Class Q1 was a class of 0-8-0T steam locomotives. They were rebuilds of the GCR Class 8A (LNER Class Q4) 0-8-0s. Thirteen were rebuilt between 1942 and 1945 at Gorton Works. All passed to British Railways in 1948, numbered 69925–69937.[1][2][3]

    Overview[edit]

    The locomotives had outside cylinders with inside valves and inside Stephenson valve gear. There were two variants:

    The extra 500 imperial gallons (2,300 L; 600 US gal) of water in the Q1/2 was carried in the rear tank, under the coal bunker, resulting in a reduced coal capacity.

    Withdrawal[edit]

    All the Class Q1 locomotives were withdrawn and scrapped from 1954 to 1959.
