Data from "Shunting Locomotive, Midland Ry," The Locomotive Magazine, Vol XIII (15 November 1907), pp. 194.
Simple little yard shunter designed by R M Deeley and produced at Derby in two batches spaced 15 years apart; 1528-1532 were delivered in 1907 and 1533-1537 came in 1921-1922. The locomotive was relatively straightforward and reflected standard British practice with the exception of the outside Walschaert valve gear installation. According to the locomotive modeler's site Brassmasters, the crews of these tanks would carry as much coal on board as they could manage: "Coal capacity was..carried in small bunkers in the cab, either side of the firebox backhead, but it was often the practice to carry an additional supply piled on the tank tops ahead of the cab."
As so often happened, this humble locomotive had a long career and the entire class was taken into British Railways upon Nationalisation in 1948. The last was withdrawn in 1967
Data from "Steam-Motor Coaches, Midland Railway", Engineering, Volume XCVIII (26 August 1904), p. 204. See also "Steam-motor Coaches for the Midland", The Engineering Review, Volume 11, No 10 (October 1904), pp. 288-290.
As several railways in Great Britain had recently put steam-motor coaches in service on branch lines, the Midland saw fit to built two of their own. Locomotive superintendent Deeley and "Mr Bain", superintendent of carriages and wagons jointly designed the vehicles. They intended to run the coaches between Morecambe and Heysham.
They had similar power dimensions and size of the vertical boiler, the power bogie's wheelbase, even valve gear to most other such cars already in use. Midland's coach had the motive power in front, followed by the luggage compartments and the vestibule over the trailing bogie. The motorman could operate the and passenger from either end using a "series of endless wire ropes carried over the outside of the roof of the carriage" to link the two regulators. A compensating lever adjusted the wire rope tension as the vehicle entered curves.
