Nationwide rollout of modern railway wireless communication

The entire railway network of Slovenia is being fitted with GSM-Railway (GSM-R). Covering some 960 km of track, this international digital radio communication system will notably increase railway infrastructure capacity and safety whilst reducing disruptions and train delays.

Additional tools


Based on traditional GSM (Global System for Mobile Communications) technology, widely used in mobile phones, GSM-R was developed in Europe as a means of ensuring safe and reliable voice and data wireless communication between trains and railway control centres. Currently selected by some 40 countries in Europe and beyond, GSM-R is part of the European Rail Traffic Management System (ERTMS) standard and European Train Control System (ECTS).

European system

Under this project, a GSM-R system is being built and installed on all Slovenia’s public railways. The objectives are to ensure interoperability and the conditions for upgrading the Slovenian railway network with ERTMS/ETCS.

Work on the core part of this GSM-R system encompasses systems for management and control. These include a core network with redundancy, dispatcher system, backbone network and transmission systems, together with equipment for management, maintenance and control.

The project, which is divided into six work packages in total, also covers base stations with their interconnection systems. These feature optical cabling for data transmission and energy supply for the stations.

Extensive new infrastructure

After completion of the project, Slovenia’s public railways will have a state-of-the-art wireless data-transmission network along 960 km of the track. Additional infrastructure includes a central dispatch centre, over 250 radio base stations, and more than 1 700 mobile devices for railways staff; plus on-board units for vehicles of the infrastructure manager. The project also covers training of relevant staff on GSM-R and maintenance of the new system for the first two years of operation.

Benefits of this GSM-R project include an increase in Slovenia’s railway infrastructure capacity and savings in signalling equipment. The new system unifies existing radio communication systems and significantly reduces disruptions to train traffic.

It is estimated that the project will create 130 new jobs.

Total investment and EU funding

Total investment for the project “Implementation of Digital Radio System (GSM-R) on Slovenian Railway Network” is EUR 149 550 735, with the EU’s Cohesion Fund contributing EUR 99 974 042 for the 2007-2013 programming period. The project falls under the “Environmental and transport infrastructure development” Operational Programme, priority "Railway infrastructure".
