A Kansas City to Northtown Yard, MN, freight is about 79 miles from the next crew change point at Wilmar, MN. Here the train crosses over the RCP&E Huron Sub along highway 23 a couple miles north of Florence. This is the Marshall Sub, a BNSF secondary mainline that twist and turn from Willmar, MN, to Sioux City, IA, with alot of the mainline tracking in and out along the Minnesota-South Dakota Stateline.
