Slowing or Controlling Speed—Scenario 1Level GradeAscending GradeDescending GradeDynamic BrakeAvailableDynamic BrakeNot AvailableSlack BunchedSlack StretchedDirection of Travel-1.10% -1.10%When slowing or controlling speed under these conditions:1. If in power, gradually reduce the throttle to IDLE.2. Wait 10 seconds.3. Activate the dynamic brake and gradually bunch the slack.4. Increase braking to the desired level.5. At a sufficient distance from the speed restriction, make a brakepipe reduction and actuate.6. Make further split reduction(s) as needed and actuate.7. When the speed is controlled and the automatic brake is released,maintain enough dynamic braking to keep the slack buncheduntil the brakes release throughout the train.NOTE: If the dynamic brake alone will slow or control thespeed sufficiently, do not use the train brakes.June 1, 1996 ARRC Air Brakes and Train Handling Manual 64-29
