Abstract
A method of propagating a brake pipe braking command along a fluid carrying brake pipe (14) interconnecting members of a transportation system, the transportation system comprising a communication system (24) for exchanging information between a controlling member of the system and controlled members of the system includes identifying an unexpected brake pipe fluid flow condition at a first controlled member (e.g. 12) of the transportation system inconsistent with a communication system braking command issued by a controlling member of the transportation system. The method also includes disabling an ability of the first controlled member to control a brake pipe flow so that a brake pipe braking command issued by the controlling member is propagated along a brake pipe to a second controlled member of the transportation system downstream of the first controlled member with reduced brake pipe fluid flow interference from the first controlled member.
