TETRA NETWORK RADIO EQUIPMENT FOR TRAIN SHUNTING

TETRA NETWORK RADIO EQUIPMENT FOR RAILWAYS

EFS manufactures radio equipment to assist shunting during train assembly (marshalling yards, station positioning).

This is Tetra network radio equipment used to establish communication between the shunter and the driver.

This global digital standard is used for professional radio communications and enable to establish reliable and secure communications.

Customer problem

An SNCF subcontractor asked us to design and manufacture radio equipment for train shunting. This device will enable communication between the shunter and the driver in complete safety when assembling trains.

• Meeting rail transport safety standards
• Communication constraints: adapting to the TETRA digital network
• Test on infrastructure currently being deployed by SNCF

EFS response

• Use of TETRA-standard digital professional radio networks
• Working with Sepura to optimize their software.

Advantages of the solution

• Ensures perfect safety for personnel during shunting operations (assembling trains in marshalling yards, positioning trains in stations, etc.).
• Secure messages: decoding by two different microcontroller.
• Use of the equipment for another application: controlling the opening and closing of level crossings.
• Use of the TETRA standard: excellent speech quality, high data rates and secure, encrypted links.
