The first phase of the Hungarian GSM-R project implemented under the control of NISZ Zrt. into the state service company in the middle of the week. All of this will ultimately benefit passengers and freighters through better information and reduced travel times. The unified GSM-R system, which features state-of-the-art technology and state-of-the-art equipment, currently provides a professional mobile communication connection along a railway line of about 1,000 km (about one-eighth of the entire Hungarian railway network).
The Hungarian GSM-R network, which is connected to Hungary, is constantly replacing the heterogeneous and increasingly difficult to operate analogue railway radio systems, so its deployment will bring serious and forward-looking changes in the Hungarian railway traffic. With the implementation of the first phase of the project, the communication system of the two major international railway corridors passing through Hungary (NE-Hamburg-Vienna-Budapest-Athens, SE: Lyon-Trieste-Ljubljana-Budapest) will become unified and interoperable. At the same time, this means that railway trains in any country can travel on the rail corridors of the member states without being hindered by differences in communication systems.
As the beneficiary of the project implemented with the support of the European Union, NISZ Nemzeti Infokommunikációs Szolgáltató Zrt. –Szolnok – Püspökladány, Szolnok – Lökösháza and Sopron – Szentgotthárd developed the service along the lines. The success of the first phase of the investment was also due to the active involvement of railway companies. The developed system is owned by the Hungarian state and is operated by MÁV and GySEV.
In the implemented phase of the project, two GSM-R exchanges operate in Hungary in a geo-redundant arrangement, ie in a geographically different location, on a separate network, so in case of any malfunction or natural disaster, it is possible to ensure business continuity. The two centers, with more than 150 outdoor and 30 indoor base stations, are also connected in a redundant manner and cover the approximately 1,000 km long railway line and all stations. To support the railway operation, a new dispatcher system was built with about 210 control and station terminals. An optical network of nearly 1,100 km was established for the modern connection of the sites, mostly in a substructure. A high-capacity IP / MPLS transmission network has been set up on the optical network, which can serve not only the traffic of the GSM-R network, but also other communications related to traffic management of railway undertakings.
the first phase of the project should have been completed as early as 2015, but this could not be achieved for several reasons. Among the official explanations is, among other things, that one of the implementing consortium members changed ownership in the meantime, and the lack of specialists at MÁV hindered the preparation and start-up.
