The 2 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-None* Wheel Profile-New 1 in 20* Spring Group 7-D5 O; 6-D5 I* Snubbing-8-9031* Snubber Augmentation-None* Centerplate Friction-Steel-STEEL* Additional Experimental Devices or Conditions-Constant contact side bearings; Long. adapter clear. is 0; Long. controls under axles* 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-040502CNE001* Track-Curved* Speed-25 mph* Outer Gib Clearance-5/8 In.* Side Bearings-7500 lb. Preload* Additional Experimental Conditions-None* Errors noted-ch. 11 -0.4v.; ch. 29 -0.3v. off 0; ch. 39 Bad ***FILE 2: Name-040502CNO001* Track-Curved* Speed-35 mph* Outer Gib Clearance-5/8 In.* Side Bearings-7500 lb. Preload* Additional Experimental Conditions-None* Errors noted-None.
