Cable cars are rail vehicles for the transportation of passengers in public short-distance traffic. Cable cars are generally driven electrically; the power supply takes place either via overhead rail tracks or the third rail. Sources of magnetic fields at the front part of wagon are the compressor of air, DC motors and choppers, at the middle part the pantograph and at the rear part the battery and the inverter.
The measured values which are provided here refer to magnetic fields caused by the overhead rail tracks when a cable car is passing by. The measurements took place either on board or at different locations near the railtracks. Measured values of magnetic fields caused solely by the overhead rail tracks without a cable car passing by can be found separately under overhead rail tracks.
