MAMAKSLOT: What's it like Developing for the Switch?

MAMAKSLOT As with overhead wires, the return current usually flows through one or both running rails, and leakage to ground is not considered serious. A very high current must therefore be used to transfer adequate power to the train, resulting in high resistive losses, and requiring relatively closely spaced feed points (electrical substations). A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a railway track. But at the same time, there were (and still are) many new third-rail systems built elsewhere, including technologically advanced countries (e.g. Copenhagen Metro, Taipei Metro, Wuhan Metro).|German Patent and Trade Mark Office
