GNR Class N1
The Great Northern Railway 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 They were all withdrawn from service between 1947 and 1959.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.
In 1914, the Crewe works built an armoured train which used a Class N1 engine. The engine was covered by 14mm steel plate, and featured observation apertures to the front and side, closed by sliding steel shutters.
