Canadian Pacific's main line along the Mississippi River through Minnesota from Saint Paul to Chicago runs through some of the Midwest's finest scenery. In addition to a variety of CP trains, the River Sub hosts Amtrak's Empire Builder and BNSF coal trains, and the Iowa, Chicago and Eastern has trackage rights. Soo Line power still heads some trains on this former Milwaukee/Soo main line. Exciting action, with a wide variety of power and paint schemes! Narration On/Off feature.
