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-Half Load* 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 Except vertical adaptor calibration should be on basis of 17.8 K* 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-010301TSR001* Track-Med. Spd. Jtd.* Speed-20 to 24 in 2 mph steps* Outer Gib Clearance-1/4 In.* Side Bearings-1/8 In. clear.* Additional Experimental Conditions-None* Errors noted-None ***FILE 2: Name-010301TWA001* Track-Hi. Spd. Jtd.* Speed-30 to 79 in 10 mph steps* Outer Gib Clearance-1/4 In.* Side Bearings-1/8 In. Clear.* Additional Experimental Conditions-None* Errors noted-ch 41 and 43 are 0.5 v., ch 44 and 46 are -0.5 v off 0.
