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 ...
