Abstract
The pneumatic braking system comprises a pneumatic circuit for supplying a pneumatic braking pressure to at least one brake cylinder, and includes a pneumatic solenoid charging valve and a pneumatic solenoid discharge valve adapted to cause an increase and a reduction, respectively, of the pneumatic pressure acting upon the at least one brake cylinder, the solenoid valves being controlled by an electronic braking control unit; a solenoid brake release valve adapted to cause, when energized, a complete discharge of the pneumatic pressure applied to the at least one brake cylinder, independently of the conditions of the solenoid charging and discharge valves; and an electric emergency line on which in normal operation there is a voltage which drops when emergency braking is activated.
