Abstract: The railroad industry has proposed an advanced system for train control. This report presents an evaluation of the system development process, with particular emphasis on the data communication system that interconnects dispatch centers, locomotives, track maintenance vehicles, and wayside devices. The report describes the proposed train control system, establishes generic requirements for collision avoidance and telecommunication system development, and analyzes the system in light of the generic requirements

Keywords: advanced train control system; collision avoidance; positive train separation; radio communication system; system architecture; data communication systems
