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 They were withdrawn between 1950 and 1958.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

Preservation

None of the G5s was preserved, although a new build is in the works 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.
