Some new locomotives, however, were built for the Midland's own use and some for the Midland and Great Northern Joint Committee and the Somerset and Dorset Joint Railway. Notable among them were the Somerset and Dorset s, a class of heavy freight locomotives for the Dorset banks, extremely large by Midland standards. Eleven were built in two batches in 1914 and 1925. A new more powerful was designed in 1911 and two were built. Quantity production began in 1917 with 192 being built in the first few years, and a further 580 after grouping up to 1940. Another remarkable engine of this period was the "Lickey Banker", designed in 1919, by James Clayton for use on the Lickey Incline south of Birmingham.
