To increase the understanding of the conditions under which wheel rolling contact fatigue (RCF) damage accumulates, wheel load environment data was collected from a car running in revenue service and analyzed to assess the predicted wheel RCF damage using shakedown theory. The car used for the...Improved Concrete Crosstie and Fastening Systems for US High Speed Passenger Rail and Joint Corridors: Volume 2
This project used basic and applied research and experimentation to address the need for an improved railway crosstie and fastening system for high speed passenger and joint passenger and freight routes in the US. The effort provided answers several concrete crosstie and fastening system design...

Measurement of Wheel Load Environment of AAR M-976 Approved Truck study (FRA Task Order 319) is the continuation of the Measurement of Wheel Load Environment of a 3-piece Truck study (Task Order 245) completed in November 2010 that increased understanding of the conditions under which wheel rolling...A Survey of Wheel/Rail Friction
Friction has a huge influence on the vehicle/track interaction and yet it remains poorly understood, its consideration an afterthought in many simulation activities. This survey of friction summarizes current understanding and identifies gaps requiring further development. Classical friction theory...Passenger/Freight Train Collision September 12, 2008, Chatsworth, CA: Main Report
