Positive Train Control (PTC) Legislation & Regulations
Positive Train Control (PTC) systems are integrated command, control, communications, and information systems designed to prevent train accidents by controlling train movements with safety, security, precision, and efficiency. PTC systems will improve railroad safety by significantly reducing the probability of collisions between trains, casualties to roadway workers and damage to their equipment, and over speed accidents. The National Transportation Safety Board (NTSB) has named PTC as one of its "most-wanted" initiatives for national transportation safety.
Pilot versions of PTC were successfully tested in xxxx, but the systems were never deployed on a wide scale. Other demonstration projects are currently in the planning and testing stages.
PTC may be voluntarily developed and implemented by a railroad following the requirements of 49 Code of Federal Regulations (CFR) Part 236, Subpart H – Standards for Processor-Based Signal and Train Control Systems; or, may be as mandated by the Rail Safety Improvement Act of 2008 developed and implemented by a railroad following the requirements of 49 CFR Part 236, Subpart I – Positive Train Control Systems.
