In recent years, there has been significant interest in the development of wireless train control systems. Among those, communication-based train control (CBTC) systems are new generation rail signaling systems, aimed at achieving real-time, automated train control through wireless communication between the train and a network of access points (APs).Radio channel characterization in railway environments is indispensable for the effective design and deployment of CBTC systems. In this paper, our recent work on the development of a physics-based wireless channel model is summarized. The validity of our developed model is verified against experimental data in various practical scenarios including the London Underground subway network in UK. On the application side, the developed physics-based wireless channel can be integrated with network-level performance metrics to optimize the placement of APs for CBTC systems. Network protocol design can benefit by harnessing a deeper understanding of the underlying physics of electromagnetic propagation in railway environments.
