How do you verify the braking system is charged before movement?

• A. Check the brake pipe pressure on the locomotive and verify brakes apply when the brakes are released.
• B. Listen for the brake shoe squeal.
• C. Inspect the air horn for proper sound.
• D. Ensure the fuel gauge is full.

Answer: (A)

Air brake systems rely on a charged brake pipe to control when the brakes apply. Checking the brake pipe pressure on the locomotive gives you a direct read on how charged the system is. If the pressure is at normal operating levels and the brakes respond correctly when you release and then reapply the brake control, you’ve confirmed the system will function properly when you start moving. The other options don’t test the braking system at all—listening for noises, checking an air horn, or looking at a fuel gauge won’t tell you whether the brake system is charged or ready to operate.
