Installation of high pressure in the brake charging network for freight trains in relation to passenger
Increased charging pressure 6,0-6,2 kg/cm2 set to freight trains weighing over 6 tons to the number of axles is not less than 350 when the pressure of 5.3 - 5.5 kgf/cm2 in the rear of the train is not attained pressure of 4 , 5 kg/cm2, as well as in freight trains of any weight and length at the forthcoming following a lengthy steep descents and more than 0,018, allowed the introduction of road charging indication of head pressure 6,0 - 6,2 kgf/cm2 for extreme driving conditions shaped trains and steepness of slopes less than 0,018.
The trains of large mass and length increased charging pressure in the head provides the minimum required under the terms of braking pressure charging 4,7-5,0 kg/cm2 in the rear of the train, taking into account the pressure drop arising from the leak.
In addition, it increases the inexhaustible brakes with frequent repeated braking due to a larger initial stock of compressed air in the brake system, which is also very important to train a large mass and length, which is recovering slowly predtormoznogo charging pressure after the release of automatic brakes.
