About this app
The Hours of Service APP was developed to provide users with clarification on Hours of Service (HOS) requirements found at 49 CFR Part 228, Hours of Service Recordkeeping, and FRA hours of service interpretations and policies. This tool allows users to navigate through Federal Railroad Administration (FRA) guidance that exists addressing the complexity of hours of service requirements, along with the diversity of railroad operations, it assists to provide comprehensive guidance and consolidating this information into one manual to ensure standardized application and compliance. Users can select from multiple railroad user groups: Freight, Passenger, Dispatching or Signal employees. The information accessed in the mobile application is not intended to be the primary reference document for hours of service requirements; 49 CFR Part 228, FRA Operating Practices Technical Bulletins, and official FRA letters addressing hours of service issues will remain the primary reference documents when dealing with Federal hours of service requirements.
