Brake trains

While maintaining a heavy freight train locomotives with electric braking in the head and part (the tail) appears the most unfavorable combination of gaps in the automatic coupling (first half of the train is compressed, the second - stretched), which contributes to improve the dynamic responses in cases of emergency braking from the head, as well as failure of electric brakes, especially if the product is not plagued by an automatic brake. Almost in these cases may break the train. To prevent this, the head locomotive engineer on the radio must without delay transmit the command of the emergency braking machinist tail engine, which the command should be immediately implemented. The more asynchronism action machinists, the higher the dynamic reactions occur. In case of failure of the electric brake is immediately followed actuated brake with full pressure in the brake cylinders and if necessary braking a crane driver.
