Proposed is a simplified analytical propagation model in railway environments. A heuristic ray tracing with geometrical optics and uniform theory of diffraction are adopted. Four typical and dominating ray paths that undergo reflections from ground and train roof and diffraction from the corner of the train are considered. The measurements verify that the analytical propagation model works very well in typical railway environments.
