Check the density of inhibitory network of freight trains
Network density is checked by full testing, as well as reduced in cases of change of locomotive brigades and cavil to the composition of a locomotive or group of cars. The test results of the density used for the control engineer trains ready for departure, after testing the brakes. An important fact is that the densities of the network when the brake test to reduce the pressure in the main reservoirs depend on the length of the train (as opposed to previously used methods for freight trains and is now used for the passenger to reduce the line pressure which does not depend on the length of the train .)
In the route of the value of leakage from the brake freight train network is one of the main characteristics of his condition, inspection of the density can be in motion and stationary. The sharp increase in leakage, accompanied by frequent switching of compressors in their long-term continuous operation, characterizes the breaking train, break in to the air outlet from the highway or the spontaneous opening of the tap on the tail end car. A significant reduction in leakage in transit in comparison with measured when testing characterizes the overlap of terminal cranes freeze or brake line.
