Factors in Lightweight Guideway Design and Costing

The effect of lightweight guideway design on ride quality is examined. Results for a particular vehicle/guideway system show that ride quality can be maintained while beam weight is reduced to a point where physical constraints or lateral and torsional strength limitations are reached. The effect...

Evaluation of Prototype Head Shield for Hazardous Material Tank Car

The structural integrity of a prototype tank car head shield for hazardous material railroad tank cars was evaluated under conditions of freight car coupling at moderate to high speeds.
