My family got me a video a couple years ago that was advertized in "Trains". I think it is called "North to the Yukon". It's put out by Catenary Video Productions. I think I see adds for their videos in "Trains" regularly. This video has 40's 50's pass. and freight operations as well as steamships on the inland passage and sterwheelers on Lake Bennett and elsewhere. It also has some rotary plow action. I give it high marks. I've probably seen it more times than I can count now and wouldn't mind watching it again some evening soon.
