Built by Howards in 1926, No 957 was used to shunt their agricultural implement and railway wagon factory sidings in Bedford. The Britannia Iron & Steel Works Ltd took over the site in 1932 to make pipe fittings and continued using it until a larger shunting loco was obtained in 1965. Through the intervention of a local enthusiast the company presented 957 to the Bluebell Railway where it was used for light shunting until about 1969. Under the auspices of the Alf Brown Group an overhaul (details of which are here) was begun in the 1970s at Horsted Keynes which had to include new wheelsets, and it made its debut at the 50th Anniversary Gala in August 2010.
Although nominally operational, at the present time more work is required to complete the restoration of the locomotive.
