System Assesses Track Condition

This article describes a system to assess track conditions for rail operators. This is a supplement to the track geometry measurement cars, which typically go over the track only once every two to six months. The new technology allows the track to “talk” to the maintenance-of-way (MOW) managers, telling them exactly where spot defects are located with great precision. The system began as a research and development project by the Federal Railroad Administration (FRA) and evolved into a joint project with a private company and Amtrak. The sensors locate the defects and report them in real-time through a Web-based system and automated email notifications. Since Acela high-speed service was started by Amtrak in December 2000, an autonomous system has been delivering information on track conditions in that corridor. Union Pacific has since adapted it for use on its freight tracks. But commuter rail has the greatest potential when they are operating over another rail operator's track and dependent on that operation’s maintenance procedures to keep track in shape. Metrolink in Los Angeles has been using the improved information on track conditions to increase speeds and decrease wear on its rolling stock.
