Improved Rail Joint Bar Designs and Maintenance Methods for use in CWR Track

Railroad track engineers are continually trying to improve the performance of rail joint performance. This article discusses how the American Association of Railroads' Strategic Research Initiatives Program, Transportation Technology Center, Inc. (TTCI) is involved in improving the performance of standard joint bars (noninsulated) in a continuously welded rail (CWR) track heavy-axle-load environment. The difference in service life between rail and rail joints is constantly increasing. The goal of improving the performance of the joint bars includes improving maintenance practices, refining manufacturing processes, improving material properties and the design of a new joint bar profile. Recent findings on maintenance practices and joint bar profiles are presented.
