From memory, the way it works is that the near short across the track by the motor damps the oscillator but the instant that the short is removed, the oscillator kicks in with a sufficiently high voltage to create an arc that blasts away the contamination so that normal traction can resume.
I've no idea how high the voltage is but I imagine that you have to be careful of putting your hands near the track when it is on!
