This report describes preliminary observations of test results at the Facility for Accelerated Service Testing (FAST) which is a 4.8 mile loop located at the Transportation Test Center in Pueblo, Colorado. The loop is divided into 22 different test track sections which permits evaluation of various types of track components and construction. The track is subjected to one million gross tons of traffic per day as a 9,500 ton train traverses the loop, running approximately 500 miles. Thirteen (13) mechanical equipment components of various designs are under evaluation in the tests. This report outlines qualitative test results for the first 6 months of testing, during which time 60 million gross tons of traffic and 31,500 miles were accumulated. This period of time represents a small fraction of the service life of most components under test and in most instances test data is insufficient for a rigorous analysis. Significantly more traffic will be necessary before valid conclusions may be drawn from the experiments.
