Opis:
One of the biggest projects aimed at integration of the infrastructure of the European Union is the implementation of the European Rail Traffic Management System on the railway network of the Member States. Its goal is to unify the railway traffic control system in European countries, increase safety as well as ensure the interoperability of rail transport. One of its main components is ERTMS/GSM-R subsystem. This article presents the structure of the GSM-R system as well as associated systems. Services offered by the system are discussed. The rules of planning radio networks including the propagation model are described. The final part of the paper contains an example of radio planning for GSM-R system for selected railway line covering computations as well as simulation tests. The simulation of the radio coverage was prepared with the usage of ICS Telecom software.

Opis:
It can be assumed that at least some of the systems associated with the train traffic operation work in the “mission” mode, i.e. their availability and operational dependability are related to safe “move” of a train through the strictly defined section of the railway line, i.e. systems (devices) must operate reliably during “mission”. In the remaining time, operation of devices does not affect the safe train traffic operation. For example, it is possible to list crossing signalling systems or the GSM-R system, which along with the ETCS 2/3 system, constitutes the ERTMS system. In the article, the GSM-R system operation analysis, in terms of the above-mentioned factors, is presented. In general, it can be assumed that the GSM-R system devices (e.g. BTS base stations) should be efficient within the specific periods, i.e. during the train passing through the relevant section of the railway line. According to the authors’ calculations, it is stated that within longer periods, the selected GSM-R system devices (BTS stations) cannot be fully efficient, i.e. possible failures occurred and removed in these periods will not affect the safe train running.
