The locomotives of the Great North of Scotland Railway were used by the Great North of Scotland Railway to operate its lines in the far north-east of the country. The railway opened in 1854 with just five 2-4-0 steam locomotives, and from 1862 it used 4-4-0 exclusively as the wheel arrangement for its tender locomotives. When it expanded by amalgamation in 1866, it inherited some locomotives from these companies. It purchased most of its locomotives, although building a small number itself, two at its first works at Kittybrewster, and ten later at Inverurie Locomotive Works.
