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 They were withdrawn between 1950 and 1958.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. 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 were preserved, although a replica, No. 1759 is under construction at Shildon.^[4] It will be built for use on various heritage lines.

Models

Bachmann Branchline have made a OO gauge model of the NER O class.
