Global System for Mobile Communications-Railways (GSM-R)

Global System for Mobile Communications-Railways Beginning 2010, 6 administrations have migrated or first step migrated to GSM-R: Germany (24000 Km), Italy (8500 Km +1100 km HSL), Netherlands (3000 Km)Norway (3000 km) and Sweden (8500 km).

Norway has finished deploying the GSM-R network, Q4 2007 they wish to migrate to the new system; Sweden has finalized their Step1 ( 8500 km) in 2003, they are now in tender for the remaining low traffic lines (1500 km); Germany finalized Step 1 end 2007 – around 24000 km; they are now implementing Step 2, which means additional 5000 km; Step 1 for Italy means 7500 km of Conventional Lines and 110 km for HSL; Conventional Lines were finalised end 2007; Finland has finalised the implementations of the GSM-R network end 2009 – 4970 km.

Meanwhile, as seen in the map railway administrations are in full implementation stage, like: Austria, Belgium, Bulgaria, Czexh Republic, Greece, Finland, France, Lithuania, Slovakia, Spain, Switzerland and UK.

Hungary, Denmark and Portugal are in tender process; Croatia, Poland, Romania, Slovenia are preparing for tender. Outside Europe, GSM-R is installed in China and India, and under deployment in Algeria, India, Turkey, and Saudi Arabia.

In Europe, from total railway network taken into account, which means 221.025 km, 150.650 are foreseen to be covered with GSM-R, which means 68, 16 %.  Taking as reference 1st of January 2010, 79.300 km of railway network are equipped with GSM-R, from which 65.800 Km are in operation, which means 43, 7% from the planned network.  According to the National Implementation Plans, 50% of the GSM-R planned network in Europe is expected to be to be in operation end 2010.

For the mobile users part, from the approximate 260.000 (we believe the figure to be bigger)users planned so far (for all European projects), 137.270 are reported to be activated, which means almost 32,9 % From this ones, 31916 Cab Radios and 1.331 EDORs are activated.

Where India Stands

Nokia Siemens Networks has implemented the first GSM Railways (GSM-R) based signaling system in India as part of the Mobile Train Radio Communication (MTRC) project for North Central Railways. The future signalling and communication requirements of Indian Railways will be modeled on the basis of GSM-R.

Earlier, the railways employed communication techniques with a single streamlined digital radio system. The new system carries signalling and operational information directly connecting the moving train driver, guard and train controller on ground. This means higher speeds and greater intensity of traffic with better security and dependability.

Networks delivered an uninterrupted GSM-R radio system, with switching, base stations and controllers, cab radios and hand held devices. Communication happens between the train controller and the drive or guard even without the need to know mobile numbers or position of the train. Networks will also provide a wide range of services together with network design, installation and commissioning, project management, training, operations and maintenance, network integration and management for one year to make sure the system works properly.

Presently, Networks has implemented the solution on a 270 kilometre section between Mathura and Jhansi. The volume of traffic is projected to double by 2014. Indian Railways has made detailed plans to eliminate snags and improve efficiency to meet its requirements

Indian Railways has selected Nokia Siemens Networks as its partner for equipping the Kolkata metro line with Global System for Mobile Communications – Railway (GSM-R) infrastructure. This will improve the safety and reliability of the Kolkata metro line while lowering operational costs for Indian Railways. Nokia Siemens Networks already supports Indian Railways’ extensive rail network spanning 3,500 km across four zones. As a result of this expansive GSM-R deployment, Nokia Siemens Networks has become India’s top GSM‑R solutions provider.

As part of its GSM-R deployments, Nokia Siemens Networks is providing compact, energy-efficient Flexi Base Stations and Flexi Base Station Controllers with improved capacity. It is supplying all operational components including switching centers, Intelligent Network (IN) platforms, service and management platforms, controller data transmission elements and mobile handsets for drivers. In addition, Nokia Siemens Networks is providing its In-Building Solution to enhance indoor coverage for the Kolkata metro project. The scope covers care services that include spare part management, software maintenance, third-party software support and training.

“Reliable railway communications is vital to address the increasing traffic density while ensuring better passenger services and safer operations. Nokia Siemens Networks’ GSM-R solution will help Indian Railways provide a better, safer service at reasonable operational costs,” said Sandeep Girotra, Head of India Region, Nokia Siemens Networks.

GSM-R ensures a reliable network that allows seamless communications on board trains running at high speeds and in diverse terrains. Nokia Siemens Networks’ GSM-R core network components such as Railway@vantage core mobility servers are designed to address railways’ demanding reliability and growing capacity requirements.
