Sixteen field tests were performed by Wyle Laboratories, Colorado Springs to measure the performance characteristics of a Type I freight car truck. Reel 15 contains test run 15. (When more than one try was required to obtain a successful run it is denoted with a letter suffix.) A pair of ASF ride control trucks were placed under an empty 100-ton open hopper carbody. New AAR 1/20 wheel profiles were used. The object of the test was to provide performance data during curve negotiation. The test was performed on March 13, 1980 on Union Pacific track near Las Vegas, Nevada. Ninety-six channels of data were acquired to measure car speed, automatic location detection, lateral/vertical wheel-rail forces, wheel/rail angle of attack, axle rotation position, accelerations and displacements at critical points on the truck and carbody. These test runs were made over mainline track between Arden and Boulder Junction near Las Vegas, Nevada. The test was run in the uphill direction with a grade of approximately 0.9%. The test was run in speed increments between 30 and 50mph. At the completion of the run, the train was brought to a stop using trainline brakes.
