During the late afternoon hour, NS 339 (Chattanooga,TN-Meridian,MS/KCS) has depart south out of Debutts Classification Yard, and is cutting through the 23rd St. (MP-338.2/243.1A) on the NS Chattanooga Terminal/ AGS North-End heading for it's destination in Meridian, MS. While on the way to Wauhatchie which is the end of the Terminal , the outbound crew is communicating to the AGS North-End Dispatcher, to get a Track Warrant to proceed out of Wauhatchie to whatever the end point of the first track warrant is required by the dispatcher. This particular manifest is usually built, and sent out of Norris Yard out of Irondale, but due to a major rise in traffic in, and out of Norris Yard, a few freights were temporary scheduled to originate, and destine for a few other terminal throughout the NS Western Region. The freight will make the late evening run to Irondale where it will bypass Norris Yard, and continue to Meridian where the train will be handed down to the KCS.
