What is the final step in the standing locomotive consist test?

• A. Actuate
• B. Release
• C. Set independent
• D. 10 psi reduction on automatic brakes

Answer: (B)

In a standing locomotive consist brake test, you work through applying and verifying how the brakes respond, then finish by returning the system to its normal released state. The last action is to release the brakes across the entire consist. Releasing completes the test and confirms that all brakes return to the unbraked condition when air pressure stabilizes, so the locomotives are ready for a parked or moving state without unintended braking. To connect the other steps: actuating checks that brakes apply when commanded; setting the independent brake tests each locomotive’s individual brake capability; and reducing the automatic brake by about 10 psi tests the automatic brake’s response to a drop in brake pipe pressure.
