If your train goes into emergency at 21 mph, with no unusual slack action and brake pipe pressure restored after stopping, are you required to walk the train?

• A. Yes
• B. No
• C. Only if instructed by supervisor
• D. Only for passenger cars

Answer: (B)

After an emergency brake application, you only need to walk the train if there are signs of problems from the stop. If the train stops and the brake pipe pressure has recharged to normal, and there was no unusual slack action during the stop, that indicates the braking system released normally and there’s no evident defect. In that situation, there’s no requirement to walk the train. You would walk only if you observed or were told to expect issues—such as continued abnormal brake demand, unrecovered air pressure, signs of dragging equipment, overheated or damaged axles, or other mechanical abnormalities.
