How does a tram operate without overhead wires?
To preserve the aesthetics of town centres, solutions have been created to enable trams to operate without catenaries :
Installing cables and poles in the heart of the city can be an ugly blemish on urban architecture.
This is why techniques have been developed to allow trams to run without catenaries, thus preserving the aesthetics of city centres:
– An on-board energy system for the tram, that works by recharging its batteries, very quickly, at each station or at the end of the line;
– A ground-based electric power supply system, which functions via a third rail placed between the two main rails, fed from boxes under the tracks.
