Braking systems of trains

In the twin freight trains to brake unintegrated highways the maximum speed of 60 km / h This level of speed due to the fact that the radio used by machinists in the management of automatic brakes, does not meet the requirements for means of ensuring the safety and possible emergency braking from the head of the locomotive without a second locomotive engineer the necessary commands. In this case, the dual brake the train stopped only by means of the first train.

Since the mass of the first train is always greater than that of second or equal to, the calculated stopping pressed at 100 m is the mass of at least 33:2 = 16.5 mc. With such a calculation by pressing the lower speed is necessary to provide the braking distance is equal to or less than the stopping distance of a freight train, which has a maximum speed of 80 km / h at 33 ton press at 100 tons of weight.

The nomogram can see that the stopping distance will be 830 meters almost the same path is obtained when the brake is pressed on the 16.5 ton mass of 100 t with an initial speed of 60 km / h This condition is kept up to 0.006 runs. On the downhill slope and the long-distance trains, both inhibit the terms of business as usual, so do not consider the case of inhibition of only one train.
