Rear-End Marking Devices

Title 49 CFR part 221 contains requirements for rear end marking devices. Railroads must give FRA a detailed description of the type of marking devices used for any locomotive operating singly or for cars or locomotives operating at the end of a train (trailing end) to ensure they meet minimum standards for visibility and display. FRA reviews and evaluates data as needed to determine if the device meets critical angle, color, and intensity requirements. This information collection is mandatory, submitted as needed, and there is a requirement for recordkeeping.
