An Itasca, WI, to Parson, KS, freight is in heavy dynamics as they drop down the .80% grade out of Chariton into the Chariton River Valley. The train is 20 miles from the Missouri border as they work south on the UP Trenton Sub. This is the old Rock Island Spineline that ran from KC to St. Paul. South of Des Moines the UP mainly uses it as a southbound corridor.
