Scanet
Encyclopedia
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 Norwegian railways
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.
However, several lines lack the system, including the Arendal Line
, the Flåm Line, the Meråker Line, the Nordland Line, the Rauma Line, the Røros Line, the Inner Østfold Line, the northern part of the Gjøvik Line, and several tunnels along the Bergen Line and the Sørland Line. The Åsta accident
in 2000 spurred the need to give all parts of the railway coverage with train radio. On these lines, the dispatcher and drivers must communicate using the Nordic Mobile Telephone
(NMT 450) standard, which by 2002 was being planned terminated by Telenor
.
Scanet was replaced by Global System for Mobile Communications – Railway
(GSM-R) in 2007. The system, delivered by Nokia Siemens Networks
, was on time and on budget, and made Norway one of the first countries to fully implement the system throughout Europe. After GSM-R was fully implemented on 1 November, Scanet was gradually closed. The new system has been characterized as simpler to use and giving better audio quality than Scanet.
Analog signal
An analog or analogue signal is any continuous signal for which the time varying feature of the signal is a representation of some other time varying quantity, i.e., analogous to another time varying signal. It differs from a digital signal in terms of small fluctuations in the signal which are...

Automatic Train Control
Automatic Train Control is a train protection system for railways, ensuring the safe and smooth operation of trains on ATC-enabled lines. Its main advantages include making possible the use of cab signalling instead of track-side signals and the use of smooth deceleration patterns in lieu of the...
