Eurobalise

Eurobalise stores infrastructure data as pre-formatted ‘telegrams’ (position reference, speed limits, line gradient, works on the line, etc.) and sends to train movement authorities and trackside data (telegrams selected by LEU) when energised by power from train's antenna.

The product is compliant with UNISIG standard “SUBSET-036 FFFIS” and “SUBSET-085 FFFIS”, thus respecting the interoperability and functionality requirements for the ERTMS and SCMT systems.

 The Eurobalise is able to operate with the principle ATP systems (KVB, EBICAD and RSDD).

Versions

Fixed-data balise sends a line data telegram to the vehicle.The telegram contains operating information
and provides details on the position of the train on the line (reference point). In the fixed-data balise, the line data telegram is stored permanently. This data can be changed by the user at any time, if required.

Variable-data balise. All signal codes corresponding to the possible signal aspects and their associated
telegrams are stored in Lineside Equipment Unit (LEU) installed at the trackside. In accordance with the signal aspect, the appropriate telegram is passed on to the variable data balise which in turn transmits it to the train. Variable data balises are connected through point to point cables with LEU that provide both data signal (telegrams) and power supply. The variable-data balise checks the quality level of the data signals received from the LEU and, in case of failure, transmits a default data telegram which is stored in the balise’s non-volatile memory.
