The NER Class O (LNER Class G5) was a class of 0-4-4T steam locomotives of the North Eastern Railway, designed by the company's Chief Engineer, Wilson Worsdell. They all survived into British Railways ownership in 1948 and their BR numbers were 67240-67349. They were withdrawn between 1950 and 1958.
Accidents and incidents
In July 1957, locomotive No. No. 67338 was used for a series of tests into the performance of concrete sleepers when trains were derailed. These tests took place between Halifax and Keighley, Yorkshire.
None of the G5s was preserved, although a new build is in the works at Darlington. Despite other locomotive project being classified as "New Builds", this one is destined to be a replica of original class member No. 1759.
