Urban transmission line for streetcar, has power supply unit supplying average power, and one supply rail electrically joined with running rail, while other supply rail is electrically distinct from running rails
The line has a low voltage power supply unit (10) supplying average power to a power supply (80) which supplies a storage unit (60) that stores energy. The power supply uses the energy for supplying a traction chain (70) during starting phase or during ascending grade. One of two supply rails is electrically joined with one of two running rails, while the other supply rail is electrically distinct from the running rails. The power supply uses the electrical energy stored during one of running phase, braking phase where electrical energy is recovered from the traction chain, or stop phase of the storing unit, for supplying the traction chain.
