Federal Railroad Administration March 3, 2023 – Federal Register Recent Federal Regulation Documents

Preliminary investigation of recent train derailments indicates the cause of, or contributing factor to, the incidents was a mechanical failure, specifically burnt journal bearings. Accordingly, FRA is issuing this Safety Advisory to make recommendations to enhance the mechanical reliability of rolling stock and the safety of railroad operations. This Safety Advisory recommends that railroads: evaluate the thresholds for inspections based on hot bearing detector (HBD) data; consider the use of real-time trend analyses of HBD data as a criterion for inspection; ensure the proper training and qualification of personnel responsible for the calibration, inspection, and maintenance of HBDs; ensure proper inspection of rolling stock with HBD alerts; and improve the safety culture of their organization, particularly as it pertains to operational decisions based on HBD data.
