Trainguard 200 RBC for ETCS Levels 1 and 2

In the case of the Trainguard 200 RBC for ETCS Level 2, the driving instructions are transmitted to the train in the form of standardized telegrams per GSM-R / Euroradio. The radio block center (RBC) receives the information about signal settings and point positions from the interlocking. The driving instructions are created alongside the stored route characteristics and can extend over several signaling sections. Since the RBC / vehicle wireless link is permanent, changes in driving instructions can be transmitted to the vehicle immediately.

The Trainguard 200 RBC also contains an extended Level 1 functionality. Information can also be sent to balises instead of by radio. This means that additional functionalities can be used in Level 1 (e.g. operable temporary speed restriction sections or long movement authorities far in excess of information obtained from the signal aspect).

The vehicle processes the transmitted speed profile, using the fixed balises along the line as electronic milestones for orientation. The vehicle also regularly indicates its location to the RBC so that its current location is known in the RBC. Since all relevant control variables are displayed to the driver in the cab, lineside signaling is no longer necessary.

Trainguard 100 for ETCS Level 1

With Trainguard 100 for ETCS Level 1, driving instructions are transmitted to the vehicle via eurobalises in the form of standardized telegrams. An LEU (Lineside Electronic Unit) is integrated in the country-specific signaling system and picks up the signal aspect directly at the signal or in the interlocking. On the basis of the signal aspect and if necessary, other information from the interlocking, a telegram customized in the LEU is selected and sent to a transparent data balise. The driving instructions are transmitted to the vehicle intermittently at the balises. Since the driving instructions cannot be updated until the train reaches the next signal, the train driver must monitor the signal when approaching stop signals.

If the signal aspect changes after passing the balise, the updated permission to proceed cannot be transmitted to the vehicle until it reaches the next balise. In case the distance between the balises is too great for the desired operation, additional balises (infill) can be placed between them. This means that the permission to proceed is transmitted to the vehicle more quickly, thereby allowing the network operator to achieve better line utilization or higher line speed on certain sections by clearing the signal aspect. At low release speed or with dense train traffic, an infill via the loop is a possible option. As a result, the new permission to proceed is transmitted to the vehicle immediately to avoid unnecessary speed reductions. In the loop area, Level 1 is a continuous automatic train control system.

With Trainguard 100/200, eurobalises transmit line information via the eurobalise/Euroloop antenna to the EVC (European Vital Computer). In the case of Trainguard 100, preprogrammed fixed-data balises are deployed, for example, to transmit line profiles to the vehicle.
