Geared steam locomotive
This gearing is part of the machinery within the locomotive and should not be confused with the pinion that propels a rack locomotive along the rack between the rails. The geared steam locomotives that have been built have been for conventional track, relying on the adhesion between wheels and rail.
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.
