Phase I of this research investigation was undertaken in September, 1996, for the Office of High Speed Group Transportation (OHSGT) og the Department of Commerce by Battelle Memorial Institute for the purpose of conceiving new and improved track structures for high-speed trains. As a result of the Phase I program, a number of track structures and fasteners were devised which met the specified requirements.
Following the conclusion of the Phase I program, the OHSGT requested additional studies and computer analyses of track structures and rail fasteners. The additional track structures of interest were chosen by OHGST from many designs which had been submitted to them. In addition to the analysis of the track structures, they were interested in a more detailed analysis of rail fasteners, particularly any analysis which was amendable to computer techniques. This project (which any then designated as Phase II) was then conducted, and the results are summarized in this report.
This report contains detailed discussion of material summarized in: “Studies For Rail Vehicle Track Structures,” PB 149 139, and is a reference source sited in that document.
