TRainCom®

The TRainCom® technology was designed and developed for new and innovative radio communication solutions supporting data services in rail applications even up to ultra-high-speed Transrapid MAGLEV trains. Today TRainCom® is the brand name of TELEFUNKEN’s product family of high- performance broadband radio systems for use in all kinds of rail applications.

The scalable system structure and architecture makes TRainCom® radio systems adaptable to all train systems – trams, light rail vehicles, metros, high speed trains and maglev trains – with velocities up to 600 km/h without any performance degradation, even in tunnels. An innovative system concept and a high transmission quality with data rates of up to 32 Mbps allows an integration of multiple communication services in a broadband environment. This not only improves operational aspects and passenger comfort, but could also revolutionize data transmission technology in the railway sector.


A TRainCom® radio system can be used for data transmissions of different services and applications:

  • Video surveillance – transfer of video data out of the moving train (CCTV)
  • Train control (CBTC/ ATO/ UTO)
  • Operational voice communication (VoIP)
  • Online diagnostic data
  • Tunnel inspection
  • Passenger counting and passenger flow management (APC)
  • Transportation management system (TMS)
  • Internet access for passengers
  • Real-time passenger information system (PIS)
  • Online advertising and merchandising
  • Passenger infotainment with online news service and TV flash
  • Online reservation and ticketing
Due to its broadband and constant link character, multiple applications can be supported simultaneously, without interference and hassle between them.
