64 Train Handling64.11.4 Stopping a Reverse or Shoving MovementFollow these steps when stopping a reverse or shoving movement:A. Stopping a Reverse or Shoving Movement—Scenario 1Level GradeAscending GradeDescending GradeSlack BunchedSlack StretchedDirection of Travel0.50% 0.50%When stopping a reverse or shoving movement under these conditions:1. Use the lowest possible throttle position to maintain a slackbunched condition.2. At a sufficient distance from the stop, make a minimum brakepipe reduction and actuate.3. Make further split reduction(s) as needed and actuate.4. Observe the load meter and reduce the throttle as necessary toavoid high buff forces.5. As the train stops, place the independent brake in FULL APPLI-CATION.6. After the independent brake is applied, reduce the throttle toIDLE.June 1, 1996 ARRC Air Brakes and Train Handling Manual 64-27

Stopping a Reverse or Shoving Movement—Scenario 2Level GradeAscending GradeDescending GradeSlack BunchedSlack StretchedDirection of TravelWhen stopping a reverse or shoving movement under these conditions:1. If in power, gradually reduce the throttle to IDLE and allow theslack to adjust.2. Wait 10 seconds.3. Activate the dynamic brake.4. Gradually stretch the slack and increase braking to the desiredlevel.5. At a sufficient distance from the stop, make a minimum brakepipe reduction and actuate.6. Make further split reduction(s) as needed and actuate.7. As speed drops below the dynamic brake range, supplement withthe independent brake.8. Make a final brake pipe reduction and allow the locomotivebrakes to apply.NOTE: If the dynamic brake is unavailable or ineffective,use the independent brake to maintain a slack-stretchedcondition.64-28 ARRC Air Brakes and Train Handling Manual June 1, 1996
