Answer: Wait for the slack to adjust
Feedback:
Going from power to Idle in this scenario will cause some buff forces. It's important to allow those in-train forces time to propagate through the train since setting the brakes will create more buff forces. High buff forces can result in derailments and damage to track and equipment. Complying with these train handling guidelines will help prevent high intrain forces and the incidents associated with them.
