The 3 data files on this magnetic tape include acceleration, force, and displacement measurements at critical points on a freight car and truck. Each file includes detailed alphanumeric descriptions of test conditions. The following are for all tests on this tape: Car-70 Ton M. Reefer* Truck-ASF Ride Control* Truck Center-45 Ft. 9 In.* Load-Empty* Wheel Profile-New 1 in 20* Spring Group 7-05O; 6-05I* Snubbing-8-3091* Snubber Augmentation-None* Centerplate Friction-Steel Moly* Additional Experimental Devices or Conditions-None* NOTE: Vertical adapter forces are subject to question. Those on sharper curves or empty cars at high speed are least accurate. Individual variations of the different tests are as follows: FILE 1: Name-010203TSM001* Track-Med. Spd.
