George Hughes produced his first class 30 locomotive by rebuiding a class 30 locomotive from his predecessor Aspinall to a four-cylinder compound engine. Ten more were created in this form. Other locomotives with two cylinders and simple steam expansion, which were built from 1910 onwards, were also assigned to class 30. 29 of these had been converted from Aspinall's class 30 and 40 more had Hughes built new at Horwich. Later they received superheaters so that they were similar to the class 31. They were assigned to power class 6F by the LMS. The last engines survived the formation of British Railways and were retired in 1951.
