An eastbound Rapid City, Pierre & Eastern train crosses a minimum maintenance road on a small trestle just west of Walnut Grove, MN. Just out of frame to the right, they'll cross Plum Creek, the locale for Little House on the Prairie, and climb a slight hill into town. The third unit is PNWR 3051. There's a chance it once traveled these rails long ago as it started life as a Chicago & North Western dynamic brake-less SD45 before being acquired by Kansas City Southern and rebuilt into an SD40-3.
