Engines are RR 10th Class 243 and ??? at Mafeking.  Train is that provided by SAR for the visit of Prince George to the Rhodesias.  White Train went through to Bulawayo after which mainly RR stock was used.  I think the date is March 25, 1934.

answer: Class 10

pmicenko
answer: Class 10B probably on the East Rand as the track is electrified and the electric suburban train in the background is in old Imperial Brown livery The hedge in the foreground and the 3000 gallon water tank would seem to indicate Springs Station. My understanding is that a few of the 10 B's were allocated to Springs shed.

Has anyone noticed the light stand behind the engines dome. Very ornate. I seem to recall some of these around Welgedag station.

I would hazard a guess at one of Capital Park's 19D locos heading back towards Pretoria, just near the Hatebeespoort Dam bridge at Meerhof, hauling a sand train from De Moot.

It is a domeless 19D and looks very much like the northern exit from Mara poorte through the Soutpansberg

And the correct answer is.....

Class 19D with domeless boiler

What people thought;

Class 4AR Zeerust line
momsmith

Class 4AR- the rotary reversing rod and the absence of front steps to facilitate access to the piston valves. Location is difficult as the prickly vegetation in the foreground puts it in a drier  area of the country. Since the 4A's were a small class in numbers and seemed to be all at Millsite shed, area is probably around Zeerust.

I know the class 4AR but unfortunately never got a chance to see one in steam, yet! Origionally the class 4A until reboilered with a standard no. 2 boiler. There are only two left in SA that I know of,  no. 1555 at Millsite and no. 1560 at Queenstown but I am not certain at this stage if they are
earmarked for cutting. A few of our drivers during the good old days were firemen on these locomotives and they tell me they were burners, meaning in the cab and on the hands when firing them. Another noticable thing on these locomotives was the fact that they were not fitted with steam reversers like all our other locomotives after the late 1920's. They were mostly used
during their days on the Krugersdorp - Zeerust Line.
