Nowadays, train control in-lab simulation tools play a crucial role in reducing extensive and expensive on-site railway testing\nactivities. In this paper, we present our contribution in this arena by detailing the internals of our European Railway Train\nManagement System in-lab demonstrator. This demonstrator is built over a general-purpose simulation framework, Riverbed\nModeler, previously Opnet Modeler. Our framework models both ERTMS subsystems, the Automatic Train Protection application\nlayer based on movement authority message exchange and the telecommunication subsystem based on GSM-R communication\ntechnology. We provide detailed information on our modelling strategy. We also validate our simulation framework with real\ntrace data. To conclude, under current industry migration scenario from GSM-R legacy obsolescence to IP-based heterogeneous\ntechnologies, our simulation framework represents a singular tool to railway operators. As an example, we present the assessment\nof related performance indicators for a specific railway network using a candidate replacement technology, LTE, versus current\nlegacy technology. To the best of our knowledge, there is no similar initiative able to measure the impact of the telecommunication\nsubsystem in the railway network availability.
