The TramWave is an innovative traction power supply system developed for light rail and tramway infrastructure that does not use overhead catenary. TramWave feeds electrical current to rolling stock safely and efficiently without using overhead contact systems or batteries and without creating traffic barriers. With TramWave, power is provided through a contact line that energizes the line only as the rolling stock vehicle passes over it.
The TramWave completely eliminates the visual impact of overhead catenary; enables easy application of power between the rails of new or existing lines; is safely crossed by pedestrians and vehicles; provides safety and availability in all working conditions; uses traction return current independent of the rails to avoid stray current; and allows for a positive and negative polarity for traction
TramWave is user-configurable for different types of vehicles (rolling stock and rubber tired vehicles.
