These 10-12-D class locomotives (the classification designated by the manufacturer) were supplied en-masse to the British War Department from 1917 onwards in all theatres, eventually totalling nearly 500 by 1918. They were the most common steam locomotive operated by the War Department Light Railways during the Great War. Based on a very similar design previously supplied to the French Army in Morocco, they had a limited life expectancy on the Battlefield of a mere 6-8 months.
Gareth Roberts, one of the event organisers of the Tracks to the Trenches event commented – Today, only a very small number of these machines have survived and an even smaller number are operational. We are extremely grateful to the Greensand Railway Museum Trust and the Leighton Buzzard Railway for making available this locomotive, fully restored to original appearance, for this important WW1 Centenary commemoration.
