Increasing capacity continues to be a major focus of the railroads as they seek to meet industry demand. Often, increasing the capacity of any given rail line can mean increasing both traffic and car loads that are run on that line, resulting in increased wear and degradation of track components. Rail field welds, in particular, are affected by wheel loads and can experience shortened life.
As part of the Association of American Railroads' Strategic Research Initiatives Program, Transportation Technology Center, Inc., is investigating improved rail welding technologies in three distinct areas:
* Assessment of weld treatment methods that may improve the ...
