This is a video I picked up some years ago - of interest to me, having grown up in the Twin Cities area. Great video, featuring action from the 70s, primarily. That was an amazing assortment of famous passenger trains that came in and out of the Cities - Burlington Zephyr, CNW 400, Milwaukee Hiawatha, Empire Builder, North Coast Limited, RI Rocket.
Every time I go back I try to take in what is now the Canadian Pacific yard just downriver from downtown St. Paul, the old Pig's Eye yard. Lots always going on there. Repair shops, hump yard, even an active turntable. I've seen a lot of Soo Line and even some (mostly unrepainted) Milwaukee engines in there over the years, among others.
