Program Plan Intro

Positive Train Control (PTC):

  • Positive train control (PTC) is a system which is used to prevent the train accidents caused by the human errors, such as train-to-train collisions, derailments caused due to excess speed, and unauthorized incursion into work zones.
  • PTC system provides audible and visual signals to the crew member regarding the slowing and stopping of the train.
  • For this purpose very high frequency wireless communication system is required.
