acquired a single self-contained railmotor for the low-volume railmotor passenger service which had been introduced the previous year. The predecessor vehicle was a railmotor engine which consisted of a single 19 Tonner 0-4-2T locomotive that was modified and semi-permanently coupled to a modified 3rd Class side-door passenger coach. On the new railmotor, the passenger coach was an integral part of the locomotive itself.Espitalier, T.J.; Day, W.A.J. (1945).

Smart that a great delay had occurred in the delivery of the two railmotors and that delivery was not expected for months. To avoid further delay with the implementing of the new railmotor service, it was decided to construct a railmotor engine at the Pretoria Works, consisting of a light 19 Tonner 0-4-2 tank locomotive and a 52-seat side-door 3rd Class suburban coach. The locomotive was modified and semi-permanently coupled to the coach, which was modified to contain a driving cab at the rear end with the controls arranged so that the push-pull unit could be driven from either vehicle. The locomotive was reclassified as a Railmotor Engine and renumbered M1. The CSAR railmotor service was put into operation in April 1906 and operated between Rissik in

Only one new Kitson-built railmotor was eventually delivered in August 1907 and was numbered M2. It was a self-contained motor-coach with a 56-seat capacity in which the engine, boiler and coach were embodied in a single vehicle. While the engine part of the vehicle was built by Kitson, the long coach part was constructed by Metropolitan Amalgamated Railway Carriage & Wagon. To negotiate curves and points, the power unit could pivot like a bogie. The railmotor was erected at the Salt River shops of the

Service


Central South African Railways

Railmotor no. M2 initially worked out of Germiston on the Elsburg-Germiston-Rietfontein Mine route, but the service was extended on 8 September 1907 to include the Germiston-Jupiter section. The route of the home-built railmotor engine no. M1 was also extended, to Hatherley-Rissik-Pretoria-Wonderboom. In service, the new railmotor no. M2 was found to be less satisfactory than the home-built railmotor engine no. M1, which was considered to be superior in aspects like design, passenger comfort, economy in running and convenience in working. With one end of the railmotor's passenger coach carried on the engine frame, the type of springs necessary for a locomotive caused unsatisfactory riding qualities in the vehicle. Since the imported railmotor was a single vehicle, the carriage was unusable while the engine had to be withdrawn for service or repairs. The Pretoria-built coach, on the other hand, was still readily detachable from the locomotive and both engine and coach were still complete units which could be used independently of each other. The purchase cost of railmotor no. M2 was £4,654, while the cost to convert the first 19 Tonner and a coach to a railmotor engine had been £5,827. Given the advantages of the home-built vehicle over the imported railmotor and the fact that several 19 Tonner locomotives were standing idle and considered unusable for any other purpose, no more railmotors were ordered and another two 19 Tonners were converted to railmotor engines in 1908, at a cost of £2,485 each. During 1909, orders were placed with the shops for another seven railmotor engines. These nine vehicles were renumbered in the range from M3 to M11. Between 1906 and 1909, steam railmotor services were expanded to operate on four routes: * Hatherley-Pretoria-Wonderboom. * Elsburg-Germiston-Rietfontein Mine. * Luipaardsvlei-Krugersdorp-Randfontein. * Germiston-Geduld.

Although the South African Railways and Harbours came into existence in 1910, the actual classification and renumbering of all the rolling stock of the three constituent railways were only implemented with effect from 1 January 1912.''The South African Railways - Historical Survey''. Editor George Hart, Publisher Bill Hart, Sponsored by Dorbyl Ltd., Published c. 1978. In 1912, the railmotor, along with the ten railmotor engines, were taken onto the SAR roster as unclassified locomotives since they were considered obsolete. Since they were excluded from the SAR renumbering schedules, they retained their CSAR engine numbers.Classification of S.A.R. Engines with Renumbering Lists, issued by the Chief Mechanical Engineer’s Office, Pretoria, January 1912, p. 2 (Reprinted in April 1987 by SATS Museum, R.3125-6/9/11-1000) At some stage, the railmotor's boiler was allocated SAR boiler no. 4001. The railmotor was withdrawn from service by 1921.
