Positive Train Control (PTC)

PTC is a predictive collision avoidance technology that can stop a train before an accident occurs. Because of its complex design and requirements, PTC is not an off-the-shelf system or software application that can be implemented quickly. The primary functions of PTC are:

  • Preventing train to train collisions
  • Preventing over-speed derailments
  • Preventing incursions into work zone limits
  • Preventing movements through a switch left in the wrong position
  • Providing interoperability between PTC systems of different railroads

PTC system provides public benefits through a reduction in risk to railroad passengers and railroad employees and would potentially improve the efficiency of the national railroad network. We provide a range of services and solutions targeted at PTC:
