Which step comes second in performing a standing locomotive consist test?

Which step comes second in performing a standing locomotive consist test?

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

Answer: (A)

The step order in a standing locomotive consist test centers on how the brake systems are checked. You want to first confirm the independent brake can be applied and holds, establishing that part of the system works. The next action is to release the independent brake, so you return the locomotive to a neutral state and can proceed to test the automatic brake functions and any subsequent adjustments. Setting the independent brake would occur before releasing it, making that the first step, not the second. Reducing brake pipe pressure or actuating the brakes come later in the sequence when you’re verifying the automatic brake response after the independent brake has been released.
