Positive Train Control
The 2008 Railroad Safety Improvement Act requires that Class I railroads implement Positive Train Control (PTC) systems on passenger routes and lines with one or more TIH (Toxic by Inhalation Hazard) cars and traffic greater than 5 million gross tons annually. PTC is designed to automatically warn a locomotive engineer of the need for action, engage locomotive brakes and bring the train to a full stop in the unlikely event that an engineer fails to act. Specific functions of PTC include preventing overspeed derailments and train-to-train collisions, protecting track workers, and preventing movement through misaligned switches. Development of PTC technology is underway at CSX, where it will affect locomotives, wayside devices and more than 16,000 miles of track. Implementation deadline across the railroad industry is December 31, 2015.
June 2015 Positive Train Control (PTC) Update
On June 24, 2015, CSX Transportation (CSX) Vice President of Service Design Frank Lonegro testified before the U.S. House of Representatives Subcommittee on Railroads, Pipelines, and Hazardous Materials about the implementation of Positive Train Control. At issue is the looming December 31, 2015 deadline for PTC implementation. Here’s a snapshot of what happened at the hearing (PDF) .
