In Britain very rarely does the need arise for a locomotive with 10 driving wheels, the only locomotives with such design include the 0-10-0 tank engine "Decapod" built by the Great Eastern Railway (GER) and the 2-10-0 British Railways (BR) standard class 9F's and of course the 0-10-0 tender locomotive built by the Midland Railway (MR) shown in the picture above.

In 1919 the Midland Railway built a single 0-10-0 steam locomotive to the design of James Anderson; its purpose was to fulfill the banking duties on the infamous Lickey Incline in Worcestershire, England (the steepest sustained main-line railway incline in Great Britain). The engine became known as "Big Bertha" or "Big Emma" by railwaymen and railway enthusiasts; as time went on she was inherited by the London, Midland and Scottish Railway (LMS) after the Midland Railway was annexed into the LMS and then inherited by British Railways (BR) when nationalization happened. With a weight of 107 tons and 10 driving wheels with a diameter of 4 ft 7 1⁄2 in, she had a tractive effort of 43,300 lbf. She was the only locomotive not given a power classification by either the LMS or BR, since she was designed specifically for the job of providing extra power over the Lickey Incline and was not suitable for normal train working. The engine was withdrawn on May 19th 1956 and scrapped by Derby Works in September 1957, having covered 838,856 miles mostly on the Lickey Incline. BR standard class 9F No. 92079 took over her roll, even acquiring Big Bertha's electric headlight for the duty. 

Here is British Railways 9F No. 92079 with Big Bertha's electric headlight.
