The Great Northern Railway (GNR) Class N1 is an 0-6-2T side tank steam locomotive designed by Henry Ivatt and introduced in 1906. They were all withdrawn from service between 1947 and 1959. None has survived.
The majority of the class were fitted with condensing apparatus and worked in the London area, from King's Cross and Hornsey Depots on empty coach trains and on cross-London exchange freight trains.
