The NER Class O (LNER Class G5) was a class of 0-4-4T steam locomotives of the North Eastern Railway,^[1][2] designed by the company's Chief Engineer, Wilson Worsdell.^[2] 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 They were withdrawn between 1950 and 1958.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.^[3]

Preservation

None of the G5s was preserved, although a new build is in the works at Darlington.^[4] Despite other locomotive project being classified as "New Builds", this one is destined to be a replica of original class member No. 1759.
