Brake trains

In the United freight train without synchronization system allowed the inhibition of only one of the first step in reducing the train line pressure up to 0.8 kgf/cm2. Restriction level determined by the force arising in the automatic coupler tail carriage of the first train and the locomotive attached to it and the head of the second train.

When connecting freight trains in the head put a heavier train. This allows the control of the head of the working cab for the most part the brakes of the train connected. Inhibition of only one parent train should not be allowed in the presence of the head of the second or the tail of the first train of empty little loaded wagons or carriages on carriages of the passenger type. Under such circumstances must inhibit both trains.
