LNER Thompson Class Q1

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
The locomotives had outside cylinders with inside valves and inside Stephenson valve gear. There were two variants:
- Q1/1 (69925-69928) with 1,500-imperial-gallon (6,800 L; 1,800 US gal) tanks
- Q1/2 (69929-69937) with 2,000-imperial-gallon (9,100 L; 2,400 US gal) tanks
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
All the Class Q1 locomotives were withdrawn and scrapped from 1954 to 1959.
