Ansaldo STS unveiled today Tramwave, a new ground-level power supply system that feeds electrical current to tramlines safely and efficiently without using catenaries or batteries and without creating traffic barriers.

With Tramwave, power is provided through a contact line that activates a small section of the line only as the tram passes over it. Tramwave is so flexible that it can be integrated in any make or model of tram, regardless of the supplier, even on currently existing fleets. This facilitates a smooth and seamless replacement of catenaries in historical locations.
