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-8-3091* Snubber Augmentation-None* Centerplate Friction-Steel-Moly* Additional Experimental Devices or Conditions-Hydraulic dampers, Long. adapter clearance 0, Long axle controls* 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-040304TSM001* Track-Med.Spd.Jtd.* Speed-15 to 45 in 5 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In. Clear.* Additional Experimental Conditions-None* Errors noted-None ***FILE 2: Name-040304TSR001* Track-Med.Spd.Jtd.* Speed-22 to 30 in 2 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In. Clear.* Additional Experimental Conditions-None* Errors noted-ch. 48 -0.5v. off 0, ch. 43 has slight noise.
