Olaf, we went to Canada in 1999, specifically for one of the longer distant trips (60 miles each way), for CN 4-8-2 6060(Stettler to Coronation). We also rode the regular train to Big Valley. I shot video from the train one day, and trackside the next. While onboard I got some good shots of the robbers who boarded the train, and had a shootout with the GOOD guy(Who was actually the RR GM) outside. The were on horseback when the train arrived.
It was a pretty good show, and entertaining. Of course they don't have the kind of scenery you have in Colorado. They had a bar car, and a couple who did broadway show tunes, a guitar player, and of course the hold-up. At Big Valley they had a big lunch, but we didn't stick around, as we headed for Jasper, for some more train action and wildlife photos. I would recommend the Albert Prairie if folks are up that way.
