Abstract

The method includes reducing pressure of a charged brake pipe to a predetermined pressure value. The brake pipe is then charged only from the head end unit. Each intermediate brake pipe monitoring and charging device sequentially reports on the network a pressure which is an increase if the brake pipe is continuous between it and the head end unit. Subsequent to receipt of a report of an increased pressure on the network from an intermediate unit, the head end unit commands that intermediate unit to participate in charging the brake pipe. The head end unit determines the brake pipe continuity from the pressure increases reported by the intermediate units.
