If a crew receives a track warrant but cannot comply with its limits, what action should be taken?

• A. Proceed at reduced speed and continue
• B. End the shift
• C. Notify the dispatcher immediately and request modification or cancellation
• D. Ignore the warrant and continue

Answer: (C)

When a crew holds a track warrant, you must operate strictly within the limits and follow the instructions provided. If you cannot comply with those limits, the safe action is to immediately notify the dispatcher and request modification or cancellation. This lets the dispatcher adjust the authority to reflect current conditions—such as occupancy, track protection, or speed restrictions—and prevents conflicts with other movements. Trying to proceed with reduced speed still outside the authorized limits keeps you operating outside planned safety protections, so it’s not an acceptable workaround. Ending the shift or ignoring the warrant doesn’t address the safety issue and could create dangerous situations on the track. When you call the dispatcher, clearly state your location, the exact limit you cannot meet, the reason you can’t comply, and what kind of modification or cancellation you’re requesting. The dispatcher will determine whether to modify the limits, cancel the warrant, or issue alternative instructions to keep operations safe.
