Answer: As the train comes to a stop
Feedback:
The final brake pipe reduction should result in the brake pipe pressure exhausting as the train comes to a stop. Setting air as the train is coming to a stop prevents a run-out of slack. Remember: Do not actuate on the final reduction since you want the locomotive brakes to apply.
