ABSTRACT: Interoperable Communication-Based Signaling (ICBS) refers to an implementation of a train control system based on signaling principles whose system architecture and interface are documented as Recommended Practices (from the AREMA Manual of Recommended Practices for Communications and Signaling) by the Association of Railroad Engineering and Maintenance-of-Way Association (AREMA). This project demonstrated that existing suppliers of vital (fail-safe) train control equipment can modify their products to support the system architecture and interfaces as specified. ICBS is capable of satisfying the requirements of a positive train control system.
