What is the maximum amount of time allowed in train service?

• A. 6 hours
• B. 8 hours
• C. 12 hours
• D. 24 hours

Answer: (C)

The question is about fatigue management and the time limit for operating a train. Crews are restricted to a maximum of twelve hours in train service to reduce fatigue and keep operations safe. Once that twelve-hour limit is reached, the crew must be relieved or take a required rest before returning to train service. The other options don’t reflect this standard safety limit: six and eight hours are shorter than the allowed maximum, and twenty-four hours would exceed safe, regulated limits.
