Timeline of train radio in Norway

Last updated

The Norwegian railway network has used two types of train radio, Scanet and GSM-R. A train radio is a mobile telecommunications network that allows a train driver, maintenance crews and other rail transport officials to communicate with a dispatcher or each other. Scanet was an analog radio system installed on the main lines, limited to electrified lines with automatic train protection, between 1995 and 1999. [1] The implementation left out many lines, which were instead covered by Nordic Mobile Telephone (NMT 450) network. [2]

The lack of a train radio on the Røros Line was a contributing factor to the Åsta accident. This spurred the demand for full coverage. [3] At the same time, the European Union required new systems to use the GSM-R standard, which will be implemented throughout Europe. GSM-R was rolled out between 2004 and 2007 and covers almost the entire network. It was also built to have 100% coverage in all tunnels, which was not achieved with Scanet. GSM-R was first rolled out on lines without Scanet, and then replaced the older system right-out. [4] Both Scanet and GSM-R consist of mobile station in the trains, base stations along the track, and a core network connected to the central traffic control centers. [1] The implementation of GSM-R cost 1.8 billion Norwegian krone. [5]


The following is a list of all railway lines with train radio. It includes the date of opening of the train radio, including the affected section, and the standard used. Freight-only lines are excluded from the list, even if they may have had Scanet or have GSM-R. [6] [7]

NMT is an automatic cellular phone system specified by Nordic telecommunications administrations (PTTs) and opened for service on 1 October 1981. NMT is based on analogue technology and two variants exist: NMT-450 and NMT-900. The numbers indicate the frequency bands used. NMT-900 was introduced in 1986 and carries more channels than the older NMT-450 network.

A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless and the network is distributed over land areas called cells, each served by at least one fixed-location transceiver. These base stations provide the cell with the network coverage which can be used for transmission of voice, data, and other types of content. A cell typically uses a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed service quality within each cell.

Scanet is a defunct, analog train radio system used by the Norwegian State Railways (NSB) and later the Norwegian National Rail Administration. The system was developed by Ascom Radiocom and was installed on the primary railways in Norway between 1993 and 1996. The system allows radio communication between a train dispatcher, and train drivers and other users involved in railway operations. Scanet has three main components: the central traffic control, base stations which are located along the railway lines, and mobile station located in the trains. The system is further connected to the internal railway telephone network, where it functions like a regular telephone. Scanet is also connected to the automatic train control system.

NSI-63 is a railway signaling system used for interlocking on the Norwegian railway network. It is based on relays and was developed by Norsk Signal Industri for the Norwegian State Railways (NSB) during the early 1960s. The systems are installed at railway stations and passing loops and consist of single relays built form drawings. The system is simple, robust and economical for smaller stations on single-track railways. The system makes use of track circuits for train detection.

The Norwegian Public Safety Network is a public safety network system based on Terrestrial Trunked Radio (TETRA). Nødnett is implemented by the Directorate for Emergency Communication. The network is primarily used for internal and interdisciplinary communication by the police, fire departments and health services. Nødnett is also used by several organisations participating in rescue and emergency work. Planning of the network started in 1995 and in 2006 the contract to build it was awarded to Nokia Siemens Networks. As Nokia Siemens Networks was unable to complete the contract, it was passed on to Motorola Solutions in 2012. The critical infrastructure of Nødnett was finished and was operational in all districts of mainland Norway by December 1, 2015.

Dr. Thomas Haug is an electrical engineer known for developing the cellular telephone networks.

Cellular frequencies are the sets of frequency ranges within the ultra high frequency band that have been assigned for cellular-compatible mobile devices, such as mobile phones, to connect to cellular networks. Most mobile networks worldwide use portions of the radio frequency spectrum, allocated to the mobile service, for the transmission and reception of their signals. The particular bands may also be shared with other radiocommunication services, e.g. broadcasting service, and fixed service operation.
