Massive Ohio Train Derailment Raises Concerns over Rail Safety: Urgent Advisory Issued on Hot Box Detectors
The Federal Railroad Administration has released a safety advisory calling on railroads to review their policies and practices for using and maintaining hot bearing wayside detectors, also known as hot box detectors. These detectors are used to measure the temperature of wheel bearings on passing trains. The advisory was issued in response to a Feb. 3 train derailment in Ohio, and suggests that mechanical failure, specifically burnt journal bearings, may have been a contributing factor. Railroads are asked to evaluate HBD data, factor in real-time trend analyses during inspections, ensure proper training and qualification of those who calibrate and maintain HBDs, and seek to improve safety culture. The FRA has identified burnt journal bearings as a possible cause of five derailments since 2021, and highlights the importance of establishing appropriate standards, processes, and procedures for the use of hot box detectors and other equipment. This information is crucial for maintaining railway safety and ensuring reliable railway operations
