Hours of Service

What ARE FRA's HOS Rules?

The Federal Railroad Administration Hours of Service (HOS) rules mandate off-duty rest periods to protect crews from fatigue and ensure operational safety. Key elements of FRA rules include:

• Maximum Duty Time: Train and engine service employees cannot be on duty for more than 12 consecutive hours. 
• Minimum Off-Duty Time: After 12 hours of work, employees must have at least 10 consecutive hours off duty before returning to work.  
• Monthly Limits: Employees are also subject to a limit of 276 total hours of service in a calendar month. 
• Interrupted Duty Tours: If a tour of duty is interrupted by a qualifying release of four or more hours at a designated terminal, the employee can return to duty to complete the remainder of the 12-hour work tour within a 24-hour period.  
• "Limbo Time" or Commingled Time: The rules also restrict the amount of time employees can spend in a status that is neither "on duty" nor "off duty," known as limbo time or commingled time, to a maximum of 30 hours per month.

What you can do with OUR HOS

• Log max/min time for any employee and specify their job type or assignment. It can track the maximum duty hours for different job types like signal operators and dispatchers, not just train and engine service employees.
• Set up federal labor rules and union-specific exceptions
• Assign duty logs with automatic violation detection
• Monitor workdays and hours in real-time
• Flag max hours, consecutive day limits, and limbo time
• Pull reports to verify and document compliance
• Give supervisors clear visibility to support daily decision-making

Also supports general timekeeping for any employee—rail or non-rail—by tracking hours.

Our Hours of Service tracks all of it—for any employee, across any type of work assignment.
