The sun poke it's head through the clouds shortly before the bottom fell out on this muggy July morning. CSX G131-15 (Hopkinsville,KY-Rockmart,GA) is down to a craw as the loaded grain train starting the trek up the north-end of Raccoon Mountain (MP J-133.0 James). What your seeing is one of the post-era Hunter Harrison's Precision Scheduling trains where the motive power arrangement is out of the ordinary. The loaded train is running in a 1x1 configuration where the lead unit is running solo on the first half of the train, and about midway out is the second unit running as mid-train dpu. Something have to do with to counter the stress on couplers on longer trains, even though this southbound is running at a 4500ft in length. This ridiculous practice is starting to be a common practice on certain schedule train throughout the CSX system.
