Radial Axle Truck Test Results Report

This report describes the performance tests conducted on a pair of prototype radial axle trucks developed by GSI. The trucks tested were purchased from GSI by Amtrak and tested by FRA as a joint FRA/Amtrak project. The results of this test show that, as configured for this test, the trucks...

Radial Axle Passenger Truck Evaluation: Life Test Results and Vehicle Performance Problems

A pair of prototype radial-axle passenger trucks was tested at the Transportation Test Center, Pueblo, Co. With steering cross-links to provide yaw-angle compliance and axle stability, these trucks can execute axle radial alignment when negotiating curves; primary suspension is made up of separate...

Prediction of Rail Buckling - Recommendations for Development of Test Methods

Railroad track structure can buckle if excessive compressive force is developed due to a temperature increase. The resulting misalignment can be a significant cause of train accidents. There is no practical method for measuring the longitudinal force without disturbing the track. Physical phenomena...
