COMBAT—A Train Control System for Secondary Lines by Radio-Based Train Detection

Abstract

There has been a growing demand for a low-cost, low-maintenance signaling system on cash-strapped secondary lines. To meet this demand, we have developed the new Computer and Microwave Balise-Aided Train Control System (COMBAT). Specific features of COMBAT are the application of microwave radio balises for train detection and centralized interlocking and block functions. This paper introduces the system configuration, its basic functions, and its benefits.
