Rolling Stock Overview

Research efforts in the Rolling Stock Equipment and Components Program area focus on the development and improvement of equipment defect detection and control. Both wayside and on-board detection and control systems offer diverse platforms for such research and demonstration.

Early defect detection greatly reduces the likelihood of equipment failure and helps prevent derailments. This program area is strongly oriented toward a proactive approach to preventing derailments, equipment failure, and undesired emergency brake applications. Risk assessment and mitigation, along with support for safety assurance are also integral elements of this program. The Rolling Stock and Components program seeks to fulfill the demands of faster, heavier, and longer trains by extending equipment and material life through early defect detection and advanced material development.
