The South African Railways Class 19C 4-8-2 of 1935 is a steam locomotive. In 1935 the South African Railways placed fifty Class 19C steam locomotives with a Mountain type wheel arrangement in service.〔 ==Manufacturer== When the need for more branchline locomotives became apparent in 1934, tenders were invited by the South African Railways (SAR) for another fifty Class 19B locomotives with Walschaerts valve gear. When the tenders were received it was found that the North British Locomotive Company (NBL) of Glasgow, Scotland, had also tendered for a locomotive with Rotary Cam Poppet valve gear.〔〔〔North British Locomotive Company works list, compiled by Austrian locomotive historian Bernhard Schmeiser〕 Even though this would increase the cost per locomotive by £200, Chief Mechanical Engineer (CME) A.G. Watson decided to adopt it in view of the good reports he had received concerning Poppet valve gear. This variation on the design led to these locomotives being classified as Class 19C when they were delivered in 1935.〔 All fifty Class 19C locomotives were erected at the Salt River shops, numbered in the range from 2435 to 2484, and many remained stationed at Cape Town while being subjected to exhaustive testing.〔 The photograph alongside shows a Class 19C locomotive after a record speed test run, during which the engine achieved a speed of .
