Title
(EN) Adaptive brake scheme during a distributed power communication loss
Abstract
(EN)

An adaptive brake system for a distributed power train responsive to an interruption in a communication system for the train and a brake application initiated at the lead locomotive, reduces the brake pipe fluid pressure at a lead locomotive and a remote locomotive to a predetermined pressure level to reduce in-train forces that may occur as a result of the pressure differentials in the brake pipe line of the lead and remote locomotives.
