Hytera Mobilfunk has supplied a secure TETRA mobile radio system for the new M4 metro line in Budapest, Hungary. This contract was awarded by its partner Siemens Convergence Creators, Austria.
The TETRA system provides secure voice communications for employees, as well as a powerful data exchange between the train-borne applications and the operation control centre (OCC). Siemens Convergence Creators is the systems integrator for the TETRA system and is also the supplier of the dispatching system and the train borne communication devices. Main contractor is Siemens Mobility & Logistics, Rail Automation, Germany.
The TETRA system comprises Hytera’s latest ACCESSNET-T IP technology and includes four TETRA base stations, two IP nodes for centralised switching in a redundant configuration, the A-CAPI application interface and a comprehensive network management system (NMS).
The metro in Budapest is the second oldest metro system in Europe and was officially put into operation in 1896 with the M1 line. The new M4 line will connect south west Budapest (Buda) to north-eastern Budapest (Pest) and is to be completed in 2014.
Siemens Transportation Systems was awarded the contract to equip Metro 4 with control and safety equipment in October 2006. The contract includes the provision of driverless control equipment, which will make the route the first to be fully automatic in Hungary when it opens.
The first 7.4km section consists of ten stations, which will connect the south western Kelenföldi pályaudvar located in Buda, and the eastern Keleti pályaudvar in Pest, under the River Danube. The second section will be an eastern extension to Bosnyák tér, while plans include a western extension to Virágpiac and further east to Újpalota.
