The NER Class G (LNER Class D23) was a class of 4-4-0 steam locomotives of the North Eastern Railway. It was designed by Thomas William Worsdell and introduced in 1887.
History
[edit]The engines were built as Class G1 2-4-0s. They had simple expansion cylinders, slide valves, and Joy valve gear. Twenty locomotives were built at Darlington Works in 1887-1888. They were initially classed as "G1" to leave the classification "G" available for a compound version. However, the compound version was not built and they were reclassified as "G" in 1914.[1]
Modifications
[edit]Between 1900 and 1904, they were rebuilt as 4-4-0s. At the same time, they were fitted with piston valves and Stephenson valve gear. Superheaters were fitted between 1913 and 1916.
Use
[edit]The engines were initially used for secondary passenger duties. By the time of the 1923 Grouping, they were working local passenger services.
Withdrawal
[edit]Withdrawals took place between 1929 and 1935 and none were preserved.
