Coming to a stop no less than 500 feet from the block, the crew of this Macon bound NS 361 (Chattanooga,TN-Macon,GA) is talking to the PTC dispatcher on trying to solve a software issue. The manifest is only 20+ rail miles south from its starting point, and had developed problem with the Positive Train Control (PTC) software, where the train would run at require track speed, than the system would trip and send the train down to a restriction speed of 10 mph. Just getting outside of the town of Cohutta, the train had to come to a stop, to explain to the Division Chief Dispatcher, and PTC-Dispatcher why the system put the train into emergency. After a briefing with the PTC Dispatcher, the train was now required to get as close as the can to the signal as seen here, and only hope that the system with override, and reset itself for the next block. To make a long story short the crew was force to run the train back into the "old method" CTC operation. Which now draws interesting question about Postive Train Control (PTC).
