Braking systems of trains

If you run heavy freight trains with electric locomotives brake in the head and part (tail) appears the most adverse combination of gaps in the automatic coupler (first half of the train is compressed, the second one - stretched), which contributes to a high dynamic responses in cases of emergency braking from the head, as well as failure of electric brakes, especially if the composition is not plagued by an automatic brake. Practically in these cases can break the train. To prevent this, the head of the locomotive engineer on the radio to transmit without delay to the command of the emergency braking of the locomotive engine driver of the tail, which is the command to execute immediately. The more drivers asynchronous action, the more there are the dynamic response. In case of failure of the electric brake immediately trigger the brake with the total pressure in the brake cylinders and brake if necessary, to strengthen the crane operator.
