Positive Train Control

To many of us, an approaching train invokes pleasant memories of panoramic views across majestic landscapes and the reassuring chug of a cozy ride back home. But the National Transportation Safety Bureau's study on rail safety throws up shocking revelations.

  • Every 90 minutes there is a train collision or derailment
  • A train carrying hazardous cargo derails approximately every two weeks in the United States
  • Further, United States train and railroad accident statistics estimate that almost every two weeks a train derailment leads to a chemical spill. Some of these spills are so serious that they require the evacuation of local residents.

PTC is a communication based safety network, which tracks and coordinates between the onboard computer on the train, the wayside signaling devices and the control center server. It is a predictive collision avoidance technology capable of preventing train-to-train collisions, over-speed derailments and unauthorized incursion into work zones.

PTC has the ability to:

  • Control and stop the train in the event of human error
  • Prevent movements through a switch left in the wrong position, and
  • Provide interoperability between PTC systems of different railroads

The Solution Canvas

PTC sends up-to-date visual and audible information to train crew members that directs them to the precise locations where the train needs to be slowed or stopped. PTC communicates with the train's onboard computer, allowing it to audibly warn the engineer and display the train's safe braking distance based on the train's speed, length, width, weight and the grade and curvature of the track. In case the engineer fails to respond to the ample audible warning and screen display, the onboard computer will activate the brakes and safely stop the train.

The benefits which can realised by implementing PTC solution are as follows:

  • Real-time incident life-cycle management and reduced legal costs
  • Framework to manage proprietary protocols and live capture of data
  • High availability and high performance
  • Preventing over-speed derailment
  • Enhance rail and consumer safety
  • Zero message loss
  • Increased crew efficiency

PTC is a solution that requires knowledge and experience in advanced ITC Systems Management. Tech Mahindra, which has been supporting mission critical applications since 1999, was selected by a major railroad technology company after an elaborately run bid in 2010 to build and deliver SMS for PTC. Tech Mahindra's PTC Testing program with North America’s largest railroad operator is widely acknowledged as one of the industries' finest. This partnership enables us bring railroad specific product offerings and SI knowledge to railroads across the world.
