A pilot project in the Vienna metro will determine how to use the energy generated from metro brakes more efficiently. The energy will be used in the metro stations for elevators, lighting and escalators and will reduce energy consumption sustainably. Public transport makes a significant contribution to the quality of life in Vienna.
Almost all metros and trams of Wiener Linien already possess the ability to recover the energy of movement (braking energy) as electric energy when braking the train, and to feed it back to the direct current power system. This energy can be used by a train in the nearest environment for acceleration. If there is no vehicle in the vicinity of the regenerative vehicle, the energy is converted into heat in the brake resistors of the train. By feeding the braking energy into the medium voltage grid, energy consumption should be reduced sustainably.
