Park Junction is near the 280 overpass of the ex-NP mainline and Minnesota Commercial's track crosses the mainline here. On this day I caught a UP coal train coming up the grade from St.Paul. This train usually has a set of helpers at the end, although I have yet to see BNSF or CPRail to use helpers on this segment. The coal train stops after clearing the Junction, and the helpers are cut off. This was sheer luck, I did not plan on this...
