Geared steam locomotive
A geared steam locomotive is a type of steam locomotive which uses gearing, usually reduction gearing, in the drivetrain, as opposed to the common directly driven design.
CGR Railmotor
A single Railmotor was delivered to the Cape Government Railways (CGR) in 1906. The railmotor was a self-contained motor-coach in which the locomotive and coach were embodied in a single vehicle, with a driver's station at the rear end of the coach for reverse running. The locomotive part was a 0-4-0 side-tank engine which was built by North British Locomotive Company, while the coach part was built by Metropolitan Amalgamated Railway Carriage & Wagon. It was the first steam railmotor to enter service on the CGR and was allocated the number 6, later M6.
