Timeline of train radio in Norway

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]

List

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]
