At a sufficient distance from the stop, actuate, then make a ___________ brake pipe reduction.
Answer: 6-8 psiFeedback: Remember to start actuating 2 seconds before making the minimum brake pipe reduction. Continue to actuate for at least 10 seconds after the brake pipe reduction to ensure the locomotive brakes don't apply. For planned stops, starting with an initial application of 6-8 psi prevents abrupt changes in slack which can occur with heavy reductions.
