RADIO TRAIN HANDLING EQUIPMENT

Radio equipment for railway maneuvering

EFS manufactures maneuvering radio equipment during the assembly of train convoys (marshalling yard, station positioning). These are communications equipment between the supervisor and the control officer. For this, the TETRA standard is used. This global digital standard is used for professional radio communications.

A the beginning

A SNCF subcontractor consults us to design a secure communication system between the driving agent and the supervisor.

Backround

The equipment environment presents communication constraints (coding security) and constraints related to SNCF infrastructure

Certification

Railway standards – TETRA standard communication

Radio equipment between chief executive officier and operator

Customer issues

A SNCF subcontractor asked us to design and manufacture radio equipment allowing communication between the supervisor and the driving agent in complete safety during the assembly of the convoys.

  • Meet safety standards for rail transportation
  • Communication constraint: adapting to the TETRA digital network
  • Test on infrastructures being deployed by SNCF

EFS Response

  • Use of TETRA digital professional radio networks
  • Collaboration with the company Sepura for an optimization of their software

Advantages of the solution

  • Ensure perfect safety of personnel during the execution of maneuvers (assembly of convoys in marshalling yard, positioning of train in station …).
  • Message security: decoding by two different microphones
  • Use of the equipment for another application: control of the opening and closing of the level crossing.
  • Use of the TETRA standard: excellent speech quality, high data rates as well as secure and encrypted links.
