Drummond designed these locomotives to answer the need for a larger and more powerful version of William Adams' 0-4-4 T1 class of 1888. The Adams T1 design of 1888 with 5 ft 7 in (1,702 mm) wheels had been developed to meet the LSWR's requirement for a compact and sure-footed suburban passenger locomotive to be utilised on the intensive commuter timetables around London. However, by the mid-1890s the suburban services around London were growing at a rate which began to preclude the use of these and other older classes of locomotive.
