If air line connections are not secure after coupling, what should you do?

• A. Notify supervisor and verify proper air line connections and brake charge.
• B. Ignore and proceed slowly.
• C. Visual check only and continue.
• D. Attempt a temporary fix yourself.

Answer: (B)

When air lines aren’t secure after coupling, the risk is that the braking system won’t function properly, which can lead to uncontrolled train movement or a brake failure. The safest and correct action is to stop, notify your supervisor, and verify that the air line connections are fully and correctly mated and that the brake system is charged before moving. This means inspecting the hoses at the couplers, ensuring the lines are properly seated and connected, and confirming the air pressure has built to the required level. If possible, perform a brake test (apply and release) to ensure the brakes respond as they should. If the connections cannot be secured, do not move the train and wait for maintenance or follow the supervisor’s instructions. Approaches like ignoring the issue, relying only on a visual check, or attempting a temporary fix are unsafe because they do not guarantee the brake system will be reliable, and could allow a loss of braking or accidental movement.
