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 They were withdrawn between 1950 and 1958.
