This paper presents a survey of contemporary problems in track structure technology and the programs of research and development addressing these problems. It reports current and anticipated investigations into aspects of the service environment of railroad track structures, the mechanics of track structure degradation, the fatigue and fracture of rails, the development of rational design and maintenance techniques, the improvement of track components, and the development of non-conventional, low maintenance track structures for application to high speed high density service. Efforts involved with both the fundamentals of track mechanics, and the design of improved structures for urban rapid transit applications, as well as mainline railroad use are included.
