Just a couple of videos from YouTube that I think are pretty good, and hope you think so as well:
First up, "White Pass Railroad," by Del McCoury, featuring some amazing old footage of the White Pass & Yukon of Alaska:

The second is "Steam Train Blues," by Chris Rea; both the footage and, even more interesting, the performer, are British. I guess the blues are international now!
