Sixteen field tests were performed by Wyle Laboratories, Colorado Springs to measure the performance characteristics of a Type I freight car truck. Reel 1 contains test run 1a. (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 run was made over branchline Class 2 track on the Blue Diamond Spur near Las Vegas, Nevada. The test zone included both tangent and curved jointed rail with an uphill grade a approximately 1.5%. The test run starts at 4 mph at milepost 4 and goes to 30 mph at milepost 5.8 and back down to a stop at milepost 8. At the completion of the test run, approximately 30 seconds of noise floor (quiescent) data will be recorded.
