Came across this website. After a quick look I bookmarked it as there is a huge amount of information and pictures of SAR steam operations, including many shots of double headed condensers on the Karoo. Brilliant stuff for all lovers of hard working steam locomotives.https://sites.google.com/site/soulorailway/home
Years ago, I bought a Goodheart Video, which at the end had a bunch of segments advertising other offerings. One was on South African steam. I've always wanted to see that one.
