Brake trains

At very long, steep slopes (up 0,030) in the first stage of braking, regardless of the length of the train line pressure reduced to 0,7-0,8 kg/cm2. This is necessary to secure all of the brakes on the train and get more of the initial inhibitory effect to reduce speed. On trains with composite shoes in winter, especially when the snowstorms, to create a reliable inhibitory effect of the first stage of braking should be done lower the pressure in the line of freight trains on 0,8-0,9 kg/cm2, empty - on 0,6-0,7 kg / cm2, and for very long, steep descents with snowfall, snow drifts first braking should perform lower line pressure at 1,0-1,2 kg/cm2. This facilitates the rapid removal of ice that forms on the surface of the friction composite brake pads. In view of the equipment of freight trains composite pads, these requirements apply to any cargo train.
