South African Railways was perhaps the most extensive narrow gauge system in the world. The steam locomotives that roamed the rails here were big narrow gauge steam. Join Machines of Iron as we go back to 1995 for a photo charter that traveled the rugged railway lines of the Drakensburg region behind garratts, 4-8-2s, a 2-8-4 and an ancient 4-6-0. Then thrill to a run down the mainline with a 4-8-4. This was a great steam train adventure that can not be duplicated today.
