64 <strong>Train</strong> H<strong>and</strong>lingA. Unusual Changes In Brake Pipe PressureThe engineer must stop <strong>and</strong> secure the train if:• An abnormal change in or loss of brake pipe pressure occurswith the train brakes released <strong>and</strong> a true gradient established.or• A brake application cannot be transmitted.B. Increased <strong>Air</strong> Brake System Leakage EnrouteFor trains with air brakes tested by the <strong>Air</strong> Flow Method, stop thetrain <strong>and</strong> repair the brake system if both of the following occur:1. Brake pipe air flow or brake pipe gradient increases.<strong>and</strong>2. The air flow pointer does not return to a reading below 60 CFMwithin the appropriate time (see Table 63-A, Charging TimeChart).NOTE: If you cannot repair the brake system to reduce leakagewithin the required limits, proceed with caution. However, do notproceed if the brake pipe pressure on the rear car is less than60 psi.C. Reporting Unusual <strong>Air</strong> Brake ConditionsFollow this process when reporting unusual air brake conditions:1. The person reporting must immediately notify the train dispatcherof any unusual air brake condition that affects safe trainmovement.2. The dispatcher must then notify the trainmaster, road foreman ofengines, or the superintendent.3. The trainmaster, road foreman of engines, or superintendent willdetermine if the train can be moved safely or if it must be heldfor inspection.June 1, 1996 ARRC <strong>Air</strong> <strong>Brakes</strong> <strong>and</strong> <strong>Train</strong> H<strong>and</strong>ling Manual 64-13
