Track Work and Signal Upgrades Near Chattanooga, TN

Jul 12, 2018


Infrastructure improvements supporting our ongoing initiative to implement Positive Train Control (PTC) are planned to begin Sunday, July 29th, near Chattanooga, TN.  This work requires a 36-hour total mainline outage with all shipments moving between Memphis and the Northeast/Southeast being impacted.  Trains will be diverted, when possible, to minimize transit and availability delays, however, delays of 18-24 hours are anticipated.

About Positive Train Control

PTC describes technology mandated by the Rail Safety Improvement Act of 2008 (RSIA) that is designed to automatically stop or slow a train before certain accidents occur. In particular, PTC is designed to prevent train-to-train collisions, derailments caused by excessive speed, unauthorized incursions by trains onto sections of track where repairs are being made, and movement of a train through a track switch left in the wrong position.
