Watching a 25NC start a 22 car passenger train from Modder river was a real treat! These engines remind me of NYC Niagaras, and they could really fly.
After you buy Greg's videos, of course, may I suggest getting a copy of "Steam Fever." It's probably the best steam video that I own. It was filmed by a professional film crew and features some great early morning steam footage, cab ride (sorry, footplate) sequences, plus some really great interviews with steam crews and the famous Dusty Durant, dean of South African rail authors. Last I knew, Goodheart video still carried it. (Dave passed away, but some friends of his are carrying on the business.)
