Web15 sep. 2024 · In a third rail system, an additional rail (also known as a conductor rail) is added to the railway. This rail carries either 600 or 750 volts in most instances (a notable exception is the Bay Area Rapid Transit, or BART, in San Francisco, which uses 1000VDC.) All third rail systems use DC, or direct current, electricity. WebHowever as third rail systems present the hazard of electric shock, higher system voltages (above 1500 v) are not considered safe. Very high currents are therefore used, resulting in considerable power loss in the system, and requiring relatively closely spaced feed …
