Abstract
In a transportation system comprising a fluid carrying brake pipe (14) connecting controlling member of the system and a controlled member (e.g., 12) a method of adaptively disabling an ability of the controlled member to respond to an unexpected brake pipe flow condition includes determining a braking state of the transportation system. The method also includes determining a degree of change in a brake pipe pressure during the braking state. The method further includes disabling an ability of the controlled member to respond to an unexpected brake pipe flow condition for a time period responsive to the braking state and the degree of change in the brake pipe pressure so that an undesired operation of the controlled member is limited.
