How to recover braking energy?
When a train brakes, it transforms mechanical energy into electrical energy. Solutions have been created
by railway engineers to recover this energy and use it to supply passenger stations with electricity.
It is now possible to recover braking energy in order to provide electricity to trains in the acceleration phase or to passenger stations. Mechanical braking energy is converted into electrical energy, then recovered via a third rail. This rail will then transfer the electricity to nearby trains, or to reversible electrical substations where the energy will be converted, thus providing electricity to the lights and lifts of the stations.
