Twelve-Hour Limit and the Last Yard Move
Engineer S. Ramirez went on duty at 06:00 for a yard assignment. At 17:35, she has 25 minutes left before the 12-hour limit. The yardmaster asks her to make one more move to clear the main track for a scheduled passenger train at 17:50. Ramirez estimates the move will take 35 minutes, including a required brake test and walking the cut. The yardmaster says 'just do the move and tie up after; it's only 10 minutes over.' The passenger train is 15 minutes away. A relief engineer is available at 18:10 but would need 10 minutes to reach the yard. Ramirez is currently on a track that does not foul the main. What should she do?
1. Can Ramirez make the move within her remaining time?
Read the worked answer
No. The 12-hour on-duty limit under 49 CFR Part 228 is a maximum, not a target. Ramirez has 25 minutes left, and her own estimate is 35 minutes, which would put her about 10 minutes over. The yardmaster's 'only 10 minutes over' is exactly the kind of exceedance the rule prohibits. Starting the move would also create pressure to skip the required brake test or walking the cut, which would be an operating rule violation on top of the hours-of-service violation.
2. What options should Ramirez pursue?
Read the worked answer
She should immediately notify the yardmaster and dispatcher that she will exceed her limit, ask for the relief engineer to be called now, and confirm whether the move can be deferred. If relief cannot arrive before her limit, she should stop the assignment in a safe condition, secure the locomotive and any cars, and tie up. She should not start a move she cannot finish within her remaining time. The dispatcher must protect the passenger train by other means, such as delaying it or using another crew; schedule pressure is not an emergency exception.
3. What should Ramirez do if the yardmaster orders her to make the move anyway?
Read the worked answer
She should refuse and document the order, including the time, the yardmaster's name, and the estimated completion time. She should state that she cannot exceed 12 hours and that she is available to tie up or perform non-operating duties until relief arrives. If the yardmaster continues to insist, she should contact the dispatcher or terminal manager and, if necessary, use the railroad's safety hotline. She should not sign a release or accept a verbal waiver. The passenger train delay must be handled through the operating plan, not by exceeding the hours-of-service limit.
