At 7,320 tons the 8,836ft long CSX Q126-04 (Savannah,GA-Memphis,TN/CN) slowly comes to a stop at the south-end crew change point at Lookout (MP J-148.1 Lookout) on the starting point of the CSX Chattanooga Sub. What was originally planned by Wauhatchie's Yard Master was to get the hot "tote" to the north crew change point at Wauhatchie, where the taxi would be waiting on the inbound crew to swap and go with the outbound crew, but counterpart CSX Q125-04 was arriving down the old main track, and before the Q126 could get close to the Terminal. So the "tote" train will wait here at the foot of Lookout Mountain for a crew change. Once the swap out is complete, the outbound crew will have to wait on the counter part CSX Q125 to clear the single main, before the dispatcher would give them a signal to shoot north up the CSX Chattanooga Sub.
