An innovative catenary-free solution
Autonomy and energy efficiency are important criteria in urban transport. With continued focus on ensuring the proper architectural integration of trams into city centres, Alstom expanded its range of catenary-free solutions with SRS, a breakthrough ground-based power charging system.
A solution compatible with all types of tramways and electrical buses
SRS is a ground-based static charging system compatible with all types of tramways, including the non-Alstom built. It is also designed to address the road market by supplying power to electrical buses through ground-based charging slots at stations or at terminus. It can be used by a large range of electrical buses.
A fast charging system
Electrical power comes from compact power supply cabinets that are smoothly and easily integrated into stations or at terminus. Collector shoes (contact blocks), fitted under the tram, make contact with the conductor rail, providing electric traction power to the tram. Supercapacitors installed on the roof of the tram store energy via a ground-based conductive rail which provides traction power to the vehicle through the collector shoes. SRS stores energy recharged during tram stations stops in less than 20 seconds.
