A 3D Scanning Method to Measure Concrete Crosstie Geometry
The Federal Railroad Administration sponsored Kansas State University (K-State) in research to improve the design and performance of crossties. K-State used a Creaform HandySCAN 700 3D hand-held scanner to scan the surface of crossties removed from service to a spatial resolution of about 1 mm,...
Mitigation of Differential Movement at Railway Transitions for U.S. High-Speed Passenger Rail and Joint Passenger/Freight Corridors
To address the need to minimize differential movement at railway transitions for joint high-speed passenger and freight routes in the U.S., this research study identified and studied three problematic bridge approaches near Chester, PA, along Amtrak’s Northeast Corridor line and another two on...
Ballast Fouling Measurement Tool – Phase II
