Train Signaling System Interference Estimation by CST MWS

This webinar presents results of the TREND project, that aims to define the conditions to control EM emissions that affect the signaling and communication systems on board of trains. We focus on the EM simulation of the interferences received by BTM antennas (Balise Transmission Module). The BTM loop-antenna is placed beneath the locomotive floor and operates as a Radio Frequency Identification (RFID) reader that interrogates balises that are distributed along the railway track as part of the European Rail Traffic Management System (ERMTS). The BTM loop is victim of radiated and conducted EM interference generated by the main current path of the train’s engine: from pantograph to the tracks. We make use of TLM solver for wire modeling and combine a high resolution mesh for the BTM antenna embedded into a model that represents Oaris, a train manufactured by CAF.

This work is supported in the context of FP7 European project TREND (Test of Rolling Stock Electromagnetic Compatibility for cross-Domain Interoperability, contract number 285259).
