Abstract
A method of and a system for minimizing undesirable brake release in the brake system of a train having a pneumatic brake on each car connected to a brake pipe which is controlled by a brake pipe controller. The method includes determining the status of the brake system throughout the train and determining a minimal brake pipe reduction for the brake pipe controller, using the status of the brake system. The determined minimal brake pipe reduction is displayed by itself or in combination with the brake pipe reduction produced by the brake pipe controller.
