The CSX SC dispatcher desk offers the Nashville terminal and the Chattanooga subdivision. The Chattanooga sub running from Chattanooga-Nashville has one of the only helper operations along the subdivision. Where every southbound train over the subdivision would need a push at Cowan, TN. The Nashville terminal subdivison requires a crew change for every train that doesn't go into Randor yard. Theres 2 locations for "Randor Crew Change" one for the Chattanooga side, and one by the yard for other trains. If both locations are filled, there is also a point in downtown Nashville they use if its backed up neaer the yard, so use it at your discretion.
