Title 49 › Subtitle SUBTITLE V— RAIL PROGRAMS › Part A— SAFETY › Chapter 211— HOURS OF SERVICE › § 21104
Railroads must not make signal workers stay on duty more than 12 hours straight. They also must not have a signal worker go on duty unless the worker had at least 10 consecutive hours off in the prior 24 hours. In an emergency, a worker may be kept on duty up to 4 extra hours in a 24-hour period, but only if the work is tied to the emergency and not for routine repairs, maintenance, or inspections. Time on duty starts when the worker reports and ends when they are finally finished. Work for the railroad during the same 24 hours counts as duty. Time spent in ontrack vehicles is duty. Travel back from a trouble call or certain trips from outlying sites to headquarters or home can be treated as neither on duty nor off duty. A meal or release period of 30 to 60 minutes is off duty and does not break continuous service; a break longer than one hour is off duty and does break continuity. Railroads and their contractors must not contact a signal worker during the required 10-hour rest in any way that would likely disturb the worker, except to notify them of an emergency as defined by the Secretary. Hours, duty time, and rest for signal workers are governed only by this law. Signal employees who drive motor vehicles are not subject to hours rules from other federal agencies, including the Federal Motor Carrier Safety Administration, except rules from the Federal Railroad Administration.
