With the deployment of the European Rail Traffic Management System (ERTMS), most of the existing groundbased signaling equipment operated along railway tracks will gradually disappear. The signaling information and command/control signals will become exchanged over Global System for Mobile communications-Railways (GSM-R). Consequently, railway signaling resilience should be re-evaluated against Intentional ElectroMagnetic Interference (IEMI) threats. In this paper we investigate GSM-R vulnerability to IEMI. These IEMIs consist in known interferers and their corresponding interference characteristics. The paper starts by describing the GSM-R communication model. Then, the interference characteristics are analyzed and progressively modified in order to study the corresponding impact on the communication. Results are presented according to these interferer characteristics and associated communication bit error rate (BER).
