Designed by the Great Central Railways Chief Mechanical Engineer John G Robinson to tackle suburban trains operating from the companys London terminus at Marylebone, they were originally designated Class 9N, however after grouping the LNER reclassified them A5. The last built locomotives, built after grouping, were assigned to north east England and under the LNER other members of the class were used more widely on suburban services from King Cross, around Bradford and on the former London Transport lines between Aylesbury and Rickmansworth. Following nationalisation those A5s still on Marylebone trains were transferred to Lincolnshire and on to Darlington and Hull. The last was withdrawn in November 1960.
