The GCR Class 9J (LNER Class J11) was a class of 174 0-6-0 steam locomotives designed by John G. Robinson for freight work on the Great Central Railway (GCR) in 1901. They were a part of the Railway Operating Division during World War 1. The class acquired the nickname "Pom-Poms" due to the similarity of their exhaust noise to that of the "Pom-Pom" quick-firing gun used in the South African War.
Career

They passed to the London and North Eastern Railway (LNER) in 1923. The LNER classified them as J11 with sub-classes J11/1 to J11/5 because of detail differences.
British Railways
The whole class survived into British Railways (BR) ownership in 1948 and their BR numbers were 64280–64453. All had been withdrawn and scrapped by 1962 and none have been preserved.
