64 <strong>Train</strong> H<strong>and</strong>ling3. Limit the locomotive brake cylinder pressure in train operationsaccording to Table 64-A. This table identifies limits for normaltrack conditions <strong>and</strong> temporary speed restrictions <strong>and</strong> turnouts.4. When operating locomotives in multiple with other units, actuate(bail off) at least 5 seconds per locomotive in the consist for fullrelease.5. When operating 1800 (GP-7) series locomotives <strong>and</strong> bailing offindependent brakes, allow extra time for air to exhaust fromcylinders to ensure that locomotive brakes are fully released.Locomotive Brake Cylinder Pressure LimitationsNumber of Axles Maximum Pressure24 or less 45 psi28 35 psi32 25 psi36 15 psi40 or more 10 psiTable 64-A. Locomotive Brake Cylinder Pressure Limitations.64.4 Throttle H<strong>and</strong>lingTo allow the train to absorb in-train forces gradually, follow thesethrottle h<strong>and</strong>ling rules:1. Make throttle changes one notch at a time.2. Use this procedure if the wheel slip light comes on:a. If the light is on continuously, reduce the throttle on thelocomotive until the light goes out.b. If the light does not go out, or if the light is blinking on <strong>and</strong>off, stop the locomotive immediately <strong>and</strong> make sure thewheels are rotating freely.64-8 ARRC <strong>Air</strong> <strong>Brakes</strong> <strong>and</strong> <strong>Train</strong> H<strong>and</strong>ling Manual June 1, 1996
