From head-end to rear-end we watch the daily run NS 147 (Cincinnati,OH-Birmingham,AL) seem to be in no hurry as the train departed the Chattanooga Terminal territory, and is on the single track main on the NS AGS North-End. Going by track warrant rules, the AGS North-End dispatcher had giving a track authority for the NS 147 to proceed from Wauhatchie to the south-end of the spring switch siding at Trenton, GA a total of about 12 rail-miles where the train will come to a safe stop, and meet a northbound freight that is following the same Track warrant rules except the northbound will go into the siding.
