s with a wheel arrangement in service. One of them was later reboilered and reclassified to Class 19R.

Manufacturer

At the request of Colonel F.R. Collins, Chief Mechanical Engineer (CME) of the South African Railways (SAR) from 1922 to 1929, the basic design of the Class 19 4-8-2 steam locomotive was done by Test Engineer M.M. Loubser, himself later to be appointed as CME from 1939 to 1949. Four locomotives were built in 1928 by Berliner Maschinenbau AG (BMAG), the former L. Schwartzkopff, in Berlin

The Class 19 family earned a reputation for reliability, easy handling, long periods between overhauls and economical operation. In preparing the specifications, Loubser gave considerable thought to the layout of this locomotive that was essentially a completely new type of branch line locomotive. The Research and Test Department was consulted on the most suitable wheel arrangement and other design details, and the end result more than justified the amount of care and thought taken during the design process.

Watson Standard boilers

During the 1930s many serving locomotives were reboilered with a standard boiler type designed by then CME A.G. Watson as part of his standardisation policy. Such Watson Standard reboilered locomotives were reclassified by adding an "R" suffix to their classification.

In 1966, when Class 19 1367 was reboilered with a Watson Standard no. 1A boiler, it became the sole Class 19R. An obvious visual difference between an original and a Watson Standard reboilered locomotive is usually a rectangular regulator cover just to the rear of the chimney on the reboilered locomotive.

The Watson Standard no. 1A boiler was designed to the same basic dimensions of the Class 19 boiler, but with more superheater elements and a different tube arrangement with larger diameter small tubes.

Service
