Positive Train Control




"Positive Train Control (PTC) refers to technology that is capable of preventing train-to-train collisions, over-speed derailments, and casualties or injuries to roadway workers (e.g., maintenance-of-way workers, bridge workers, signal maintainers) operating within their limits of authority as a result of unauthorized incursion by a train. PTC is also capable of preventing train movements through a switch left in the wrong position. PTC systems vary widely in complexity and sophistication based on the level of automation and functionality they implement, the system architecture utilized, the wayside system upon which they are based (i.e., non-signaled, block signal, cab signal, etc.), and the degree of train control they are capable of assuming." - FRA.

HCRQ is proud of its PTC experience.

We monitored the progress of the RSAC PTC working group and 49CFR236 Subpart I. Ultimately, the FRA published the PTC System Final Rule on January 15, 2010. Look for our name in this rule! It appears 44 times.

Coincident with the new 49CFR236 Appendix F (Minimum Requirements of FRA Directed Independent Third-Party Assessment of PTC System Safety Verification and Validation). HCRQ offers this service.

For more information on PTC we refer you to the FRA PTC web page and the AAR PTC web page.
