South African Class 19C 4-8-2

The South African Railways Class 19C 4-8-2 of 1935 was a steam locomotive. In 1935 the railways placed fifty Class 19C locomotives with a 4-8-2 Mountain wheel arrangement in service, the first South African class to use rotary cam poppet valve gear and the first built new with a Watson Standard boiler. When tenders were invited in 1934 for more branch line engines, the North British Locomotive Company of Glasgow tendered an alternative with rotary cam poppet valve gear, and chief mechanical engineer A.G. Watson accepted it despite a cost of 200 pounds more per locomotive. All fifty were erected at the Salt River shops in Cape Town, numbered 2435 to 2484, and they were withdrawn from service in 1978.
