// two-system vehicle (3 kV dc and 25 kV ac): voltage relays recognize the system on each pantograph, each system has
// its own line breaker, the ac branch has a transformer, both branches feed one bus with the converter (230 V~ auxiliary
// circuit for the compressor, 110 V= low voltage for a lamp). body:mains is closed when any of the breakers is
