Track/Train Interaction Overview

Track/Train InteractionThe Track/Train Interaction Program addresses the safety implications arising from the dynamic interaction between track and train.  It will improve analytical and experimental methods for assessing derailment risk due to anomalous interactions of track geometry and railcar suspension system, provide improved guidelines for rail grinding or lubrication that will facilitate optimum wheel-rail contact and truck steering in heavy load and high-speed situations, and develop a comprehensive computer program for modeling and simulating railway vehicle/track systems, with an emphasis on the dynamic performance of both vehicle and track and their interactions through the wheel/rail interface.  This program will support the development of performance-based standards and guidelines for vehicle/track interaction safety and ride quality, and of safety standards and guidelines for transverse wheel and rail profiles.
