A fourth possibility would be electrified studs in the street, with the power activated as a streetcar passes over them. I don't know if this method has ever been used in actual service anywhere.See Tramway de Bordeaux's Alimentation par Sol system as designed by Alstom. It's effectively a third rail system that powers up as the tram approaches each 8 meter segment of third rail. Bordeaux in its past once had a conduit based tram network that was replaced with buses like DC. Angers and Reims are expected to have the same set up for their tramways. FWIW, the other alternative to APS is Bombardier's Primove system where power is transferred via induction to the streetcar. It's currently running as trial on a small branch line of Augsburg's streetcar network. |
