ABTH Train Handling Verbatim Quiz

1. Reduce the throttle before the locomotive crests the grade. 2. Continue to reduce the throttle to keep the speed from increasing until at least half the train has crested the grade.

Slowing And Controlling Speed On A Cresting Grade (2 Steps)

1. Release the automatic brake. 2. After the brakes have released on the entire train, move the throttle to RUN 1 and release the independent brake. If the locomotive moves too rapidly in RUN 1, control surge with the independent brake. If the train does not move, slowly advance the throttle. 3. Use the lowest possible throttle position to minimize in-train forces. 4. After the train starts to move, check to see if the amperage or tractive effort levels are decreasing. If these levels are decreasing, you may advance the throttle to the next higher position.

Starting A Train On Level Grade (4 Steps)

1. Gradually reduce the throttle one notch at a time. 2. Maintain a slack stretched condition and allow the ascending grade to slow the train. 3. When the train stalls, place the independent brake in FULL APPLICATION. 4. After the independent brake is fully applied, reduce the throttle to IDLE. 5. Apply train brakes as the train stops or just before it stops if immediate movement after stopping is not anticipated.

Stopping On Ascending Grade Using Throttle Modulation Method - Slack Stretched (5 Steps)

1. 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 stop, make a minimum brake pipe reduction and actuate. 6. Make further split reduction(s) as needed and actuate. 7. As speed drops below dynamic brake range, supplement with the independent brake. 8. Make a final brake pipe reduction and allow the locomotive brakes to apply.
