Train monitoring systems: uncompromising safety.

At SBB Infrastructure we operate and maintain the busiest rail network in Europe. By monitoring trains and those parts of the rail network which are particularly exposed to potential dangers, we reduce risks to a minimum.

Our train monitoring systems make the railway infrastructure safer and increase its availability. Within Switzerland, we have systematically established, developed and networked automated train monitoring. By installing train monitoring systems across the network, SBB is making a significant contribution to the safety of rail traffic and to increasing the availability of train paths in Switzerland.

Measuring systems for enhancing safety.

  • Wheel load check point (RLC).

    Detects load displacement, overloading and wheel defects.

  • Fire detection (BOA).

    Prevents safety-critical situations arising due to fires.

  • Hot axle boxes and locked brakes detector (HFO).

    Checks the temperature of axle bearings, wheel rims and brake discs and makes it possible to prevent derailments caused by axle and wheel failures.

  • Out-of-profile and antenna detector (PAO).

    Detects clearance gauge violations and instances of vehicle antennas, tarpaulins or displaced loads touching the overhead contact lines.

Measuring systems for increasing route availability.

  • Natural hazard alert systems (NGA).

    Monitor the network to guard against rockfalls, landslides, debris flows and avalanches.

  • Dragging equipment detection (DED).

    Detects objects hanging below or dragged along by vehicles so as to prevent damage to the track area, especially to Eurobalises.

  • Uplift pressure measurements (AHM).

    Monitor the upward pressure exerted by pantographs so as to prevent damaging the overhead contact line.

Measuring systems for improving operating procedures / maintenance quality.

  • Radio frequency identification (RFID).

    Records the RFID tags attached to the wagons; this permits measurement readings to be attributed to specific axles, thus creating a series of measurements over longer periods of time.

  • Visual inspection system (VIS).

    Records images of the whole train from all perspectives (sides, top, bottom) so that RUs and vehicle keepers can evaluate the data so as to improve / automate their processes.
