Sixteen field tests were performed by Wyle Laboratories, Colorado Springs to measure the performance characteristics of a Type I freight car truck. Reel 16 contains test run 16a. (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 February 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. This test was run over yard track in the Las Vegas Yard and included curves of 12 and 16 degrees. The run was made in a forward direction at 10 mph and then backed through the test zone at 10 mph.
