John,
Your second photo looks like the railfan version of question: How many angels can dance on the head of a pin?
That was indeed David's last South Africa tour. Others have run some shorter trips, but that was the last of the serious tours. Getting the old red and cream coaches and sleepers was a challenge, since they had all been downgraded from regular passenger service, but the photo results were worth it. Seven different Cape Gauge loco classes and one Narrow Gauge loco vs. up to 25 different classes back in the day, but compared to what I previously shot on film, the 2007 trip was the best ever, photographically. Shooting South Africa on digital was a real treat.
