CSX M783-27 (Nashville,TN-Chattanooga,TN) is easing down grade on the main 2 track heading straight for Wauhatchie Yard during the late evening hours on the CSX Chattanooga Sub. To set the tone a little different, for the assigned power on today's train is a matching pair of the CSX 4000 series SD40-3's. The rebuild Sd40's are a sight that is often accepted from the railfan prospective, and earn the name dub "SpongeBob SquareCabs" for its rather unique Safety Cab that stand out of this locomotives . The short train will run at least a half of a mile to the Wildwood Control-Point (MP J-143.4 Wildwood) where they will wait on Q143 to get into the clear off the yard lead, where M783 will get the restriction signal to proceed down the lead to Yard track #3 completing the days run.
