System weighs railcars moving up to 14 mph

LegalWeight, Schenck Process’ railcar weighing system, is designed to weigh railcars in motion. The design uses instrumented concrete weighing ties equipped with high-precision load cells that accurately measure vertical force, according to the company. Installation of the weighing system is done without a pit and is mounted directly on top of the ballast, reducing overall installation time to two days or less for most applications. LegalWeight is integrated into the existing rail without any gaps or joins in the rail. Track downtime is reduced compared with older designed pit-type scales, the company adds. LegalWeight can operate legal-for-trade at weighing speeds up to 14 mph. When trains are not being weighed they can travel at the typical line speed for the track.
