The Great Northern Railway (GNR) Class O1 was a class of two-cylinder 2-8-0 steam locomotive designed by Nigel Gresley for heavy freight work and built by the GNR between 1913 and 1919.

The O1 had two 21in diameter cylinders powered by a 5ft 6in diameter boiler which was fitted with a 24-element Robinson superheater. The O1 was Gresley's second design for the GNR and he incorporated a number of features from his first design, the K1 2-6-0.

As is customary, engine classes are organized according to the man who was locomotive superintendent when the class was introduced, and to whom the design is often attributed. Six men held this post during the existence of the Great Northern Railway.

Here we have a well made 5" GNR 01 class 2-8-0 locomotive to Martin Evan's 'Nigel Gresley' design. The work to date is to a good standard, and we've had the chassis running well on air. The boiler has been hydraulically tested to twice working pressure (standard shell test), is brand new and soundly made.
