In countries for instance France, South Africa, Australia and the United Kingdom, a set of long term magnets beside the rails at possibly side of your neutral area work a bogie-mounted transducer within the coach which brings about a large electrical circuit-breaker to open and shut once the locomotive or maybe the pantograph automobile of the numerous device passes around them.
On DC devices, bipolar overhead traces had been in some cases applied in order to avoid galvanic corrosion of metallic components close to the railway, for example around the Chemin de fer de la Mure.
