Flexible Broadband Simulation of Balise Crosstalk Using a Modal Transmission Line Equivalent Circuit Model

Balise crosstalk along railway track structures represents a significant challenge for the reliable transmission of train control information. This paper presents a SPICE-compatible modal network model for the efficient broadband simulation of electromagnetic coupling effects. By deriving the equivalent circuit parameters analytically, the influence of factors such as structure length, damping, and load conditions can be investigated flexibly without relying on extensive measurements or complex 3D simulations.

This paper explains the derivation of a modal transmission line equivalent circuit model for simulating balise crosstalk and demonstrates its application in a realistic railway scenario. Measurement and simulation results are compared to show how coupling effects can be analyzed and assessed efficiently.

Learn how electromagnetic coupling mechanisms in railway environments can be evaluated quickly and efficiently using a flexible, physics-based simulation approach.
