RFID technology expansion.
The majority of rail vehicles have already been fitted with two RFID (radio frequency identification) tags each.
RFID readers at the edge of the track identify the vehicle number contactlessly when the train passes, enabling seamless tracing of vehicles. By 2020, SBB will have equipped all ZKE locations with RFID readers. SBB makes the measured data available to railway undertakings, allowing them to better plan their vehicle maintenance, among other benefits.
