Radio Propagation in Railway Corridors Through Dense Forests–Measurement and Modeling at 460 MHz
Radio Science, Volume 61, Issue 3, March 2026.Abstract Current train signaling systems are being replaced by advanced systems like Communications‐Based Train Control, European Rail Traffic Management System, and Positive Train Control, which rely on radio networks. However, railways operating in dense forest environments face unique challenges for wireless systems due to high levels of signal ...

Ten Diverse Formal Models for a CBTC Automatic Train Supervision System [PDF]
Electronic Proceedings in Theoretical Computer Science, 2018 Communications-based Train Control (CBTC) systems are metro signalling platforms, which coordinate and protect the movements of trains within the tracks of a station, and between different stations. In CBTC platforms, a prominent role is played by the Automatic Train Supervision (ATS) system, which automatically dispatches and routes trains within the ...

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.This study considers scenarios where mainline and branch line trains can pass through switches at different speeds, and conducts a decision analysis on the locations (sections or stations) for train formation. The definitions and calculation methods for allowable virtual coupling and decoupling distances are proposed to determine whether trains can ...
