Abstract:
Railway management systems are based on a centralized structure where the Central Post centrally manages all the components, trains and railways, with the aim to guarantee the safety of the service and the efficiency of the network capacity. This architecture requires an extended exchange of information between management units, monitoring systems and actuators. In general, the communication is based on wired links that ensure required performance, but present also some drawbacks. For instance, copper cable-based links are affected by cables thefts or can limit the type and the amount of information that can be sent due to the capacity of involved technologies. In all these scenarios, the introduction of a wireless link can improve the safety, the performance and the flexibility of the communications. In this paper, the use of wireless communications as backup or extension of the pre-existent wired links is deepened. Trackside and on-board communications, as well as European Rail Traffic Management System and EURORADIO protocol are studied analyzing the issues related to wired links and illustrating how the use of wireless communications can face off their drawbacks.
