Nowadays large part of railway vehicles is able to combine the standard pneumatic braking to an electrical braking system, made possible by the electric traction system. In this way, the kinetic energy of the train is converted in electrical energy, which can be handled in different ways.
When the state information detected by the sensor is transmitted to the energy management system, the energy recovery device will first be engaged to provide braking torque, with disc braking being complementary. In this way, the braking system can largely reduce the wear and extend its service life.
To enhance energy recovery during braking, otherwise constrained by the need to have of other trains that at the same time are adsorbing power in the vicinity as in other typical railway applications [ 8 ], the utilisation of some energy storage has been foreseen.
