TRS2090 is a digital train radio system (provided based on TETRA or DMR), which sets a new standard in the modern Railway communications industry. During the development special attention was drawn to the fact to have as many GSM-R like functionalities as possible in order to be able to offer an excellent alternative to the European GSM-R standard. The great advantage for railway customers is to obtain a similar high-end technical product at a much more reasonable price level. In comparison to GSM-R infrastructures the implementation as well as the operation of TETRA- or DMR- infrastructures is much cheaper for finally getting similar railway network functionalities.

Besides the usual important GSM-R typical functionalities the train radio system often contains other individual customer specific railway applications and functionalities as well as menu structures for the daily operational business, which are subject to detailed technical specification between ErvoCom International and the client prior to a project rollout. This is efficiently possible thanks to the modular system concept of TRS2090. Additionally to the standard functionalities like voice communication the TRS2090 provides further railway specific features, e.g. emergency call, call preemption according to priorities, passenger announcements into the train, text messaging (SDS), functional registration, train running number based calls and more.

Depending on the individual project requirements the TRS2090 system consists of a combination of a central controller unit (ZSE2130) in conjunction to one or two remotely connected human machine interfaces (CoCo2137/CoCo2167/CoCo2177).

The following basic functionalities are provided:

  • Voice communication with transmission and reception of text messages
  • Data communication from/to on-board computer systems
  • Emergency communication
  • Creation of dynamic groups for specific scenarios
  • Passenger announcements into the train (train driver initiated call or dispatcher initiated call)
  • Possibility of interconnection to passenger information systems (PIS), INTERCOM (IC), e.g. emergency call terminals for passengers
  • Interfaces to audio accessories, e.g. handset, gooseneck- or palm microphone, etc.
