This report presents analyses of data, up to 50 million gross tons of traffic, from the Facility for Accelerated Service Testing (FAST). These analyses include concrete and wood tie track system performance and component performance, rail wear comparisons, ballast depth and type performance, ballast shoulder width, and subgrade performance. In addition, there is a summary of general FAST results to date which includes coments on the major maintenance performed on special trackwork and other sections of the track not specifically addressed in the main chapters of the report. Also, some of the information contained in this report was derived from data from other sources such as the Velim test track in Czechoslovakia.
