Positive Train Control

Overview

E-ATC is a system that uses an underlying automatic train control (ATC) system, in conjunction with other “enhanced” features or systems to achieve the core required functionalities of PTC. These systems are often integrated with underlying cab signal systems (CSS) and centralized traffic control (CTC) systems, in addition to other signal or train control system enhancements the railroad elects to make, to meet the full requirements of PTC.

A PTC System:

  • Prevents train-train-collisions
  • Prevents derailments caused by excessive speed
  • Prevents unauthorized incursions by trains into work zones where maintenance activities are taking place
  • Prevents movement of a train through a track switch left in the wrong position.
