Performance Evaluation of Mechanical Rail Joints

This article describes a performance evaluation of mechanical, or non-insulated, rail joints in revenue service main lines. Although joint-related accident rates have been falling, better information on the performance of rail joints will help the industry to better allocate resources towards improvement. The authors describe mechanical rail joints and the effects on them generated by railroad car wheels. The authors relate there are about 143,000 joints or 286 joint bars in main line service. Their findings suggest the need for more rigorous modeling and testing to better understand the relationship between load environment and the behavior of the joint bars. They also suggest that joint design should more closely match the life expectancy of the parent rail, and that rail fabricators should work more closely with track engineers to develop a better foundation for the joints.
