Wonderful images, Kevin!
And thanks for all the background information. The Wiki article on the 15F class includes an image of David Shepherd and his wife Avril and the painting you displayed.

Wiki also has what appears to be a very good, well-illustrated, article on the 19D Mountain locomotives (Dollies?):

4-8-2 seems to be a popular wheel arrangement in South Africa.
I am learning a lot of new information from your thread, Kevin.

PS: Yesterday, I was picking up my car from the auto shop just outside Carlisle Barracks, where the Norfolk Southern line runs past. A pair of GP38-2s (5265 and 5268) rumbled past with a short string of freight cars (goods wagons), and I had left the camera at home!
As an interim measure, here is an image of one of our local locomotives, 5268, taken at Montsera, Pennsylvania, a tiny crossroads a few miles from where I live:
