Abstract
A braking system for a train comprises a pneumatic brake pipe (BP), which extends along the train, and in which the pressure is controlled by a braking control apparatus (BCA) in the locomotive (L), and an electrical power supply and signal line (EL), which equally extends along the train, and which is linked to an electronic control unit (ECU) in the locomotive. Each wagon (W) in the train comprises a pneumatic brake valve (ELV) coupled with the brake pipe (BP) and suitable for applying to brake cylinders (BC) of the wagon (W) a brake pressure that is a function of a control pressure applied to a control input (CI) thereof; and an electro-pneumatic control assembly (EPC) including solenoid valve control devices (EVF, EVS), coupled with the brake pipe (BP) and with which a first pressure accumulator (DVE) is associated.
