Title 49 › Subtitle SUBTITLE V— - RAIL PROGRAMS › Part PART A— - SAFETY › Chapter CHAPTER 211— - HOURS OF SERVICE › § 21104
Railroads and their contractors must not make signal workers stay on duty more than 12 hours in a row, and they must not let them start work unless the worker had at least 10 straight hours off in the previous 24 hours. In a real emergency, a worker can stay on up to 4 extra hours in a 24-hour period, but not for routine repairs or inspections. On-duty time starts when a worker reports and ends when they are finally released. Time doing other railroad work that day counts as on duty. Time spent riding an on-track vehicle counts as on duty. Time spent returning from a trouble call or traveling after scheduled hours from an outlying worksite to headquarters or home is treated as neither on duty nor off duty. A meal break of 30 to 60 minutes is off duty but does not break the work period; a break over one hour does break it. During the required 10-hour rest, carriers may not contact the worker by phone, pager, or other means that would likely disturb their rest, except to tell them about an emergency. Hours and rest rules for signal workers are controlled only by this law; other federal hours rules (like FMCSA rules) do not apply, except rules from the Federal Railroad Administration.
