The Great Northern Railway (GNR) No. 1 class Stirling Single is a class of steam locomotive designed for express passenger work. Designed by Patrick Stirling, they are characterised by a single pair of large (8 ft 1 in) driving wheels which led to the nickname "eight-footer".

These engines, 16 in number, were built to the following dimensions: cylinders lyi-in. by 24-in., diameter of driving wheels 5-ft. 1-in., and of bogie wheels 3-ft. The total wheelbase was 22 -ft. 6-in., the coupled wheel centres being 7-ft. 3-in. apart, and the bogie wheel centres 5-ft.

Stirling built his engines for speed and power, in order to handle some of the continuous gradients on the main York-London GNR line, and to compete against the Midland Railway and L&NWR in the Races to the North. Stirling joined the GNR in 1866 having previously been Locomotive Superintendent of the Glasgow & South Western Railway since 1853.

Gresley’s first new boiler design (ordered January 1912) was used to rebuild 4-4-0s from Class D2 (LNER D4) to Class D3 (LNER D3) and 0-6-0s J5 (LNER J4) to J4 (LNER J3). Also used for 0-6-0s J9 (LNER J7). In effect the engines were rebuilt with 4ft.-8in. diam. boilers in place of 4ft.-5in.
