STEAM LOCOMOTIVE CLASSES USED IN SOUTH AFRICA


THE FABULOUS CLASS 19D

class 19DThe class 19D is still currently being used daily on the route between Knysna and George, hauling a 5-coach passenger train of old wooden coaches along a very mountainous scenic route. Infact, two trains with 19D's run in opposite directions daily, either used by locals just as transport, or by visitors for pure fun. I believe Rovis Rail also make use of a running 19D. Here's some general specifications by Friends of the Rail:

Tractive effort: 31,850 1bs at 75%
boiler pressure: 200 1bs
cylinders: 21" x 24"
Coupled wheels diameter: 4'6"
Wheel configuration: 2-8-4
Heating surface: 1,700 square feet
super heater area: 404 square feet
firegrate area: 36 square feet.

The 25NC's were the last class of main line steam locomotive built for South Africa. These massive 4-8-4's were a popular and successful engine, famous around the world for their main line work on the Kimberley - De Aar main line until the early 1990's. 3404 was fortunate in that she was one of 4 25NC's kept for work on the Trans-Karoo passenger train until 1997. Each Friday, a pair of 25NC's would haul the Trans-Karoo from Johannesburg to Klerksdorp, then the return working to Johannesburg on the Saturday. This loco was stored at Braamfontein until recently, when it was transferred to Germiston Loco Depot for storage until we are able to move it to Capital Park. This loco is basically in running order but will require inspection and certification before steaming again.
