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-None* Wheel Profile-Worn* Spring Group 7-D7O; 6-D7I* 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-020205TWA001* Track-Hi.Spd.Jtd.* Speed-30 to 79 in 10 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-3/8 In.Clear.* Additional Experimental Conditions-None* Errors noted-ch. 19, 40, 48 Inop.; ch. 12 No Neg.; ch. 10 +1.0v off 0; ch. 29 +0.4v off 0; ch. 26, 36, 39 questionable ***FILE 2: Name-020205TEM001* Track-Hi.Spd.CWR* Speed-30 to 60 in 10 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-3/8 In.Clear.* Additional Experimental Conditions-None* Errors noted-ch. 19, 48 Inop.; ch. 12 No Neg.; ch. 26, 36, 39 questionable ***FILE 3: Name-020205TEH001* Track-Hi.Spd.CWR* Speed-70 and 79 mph* Outer Gib Clearance-5/8 In.* Side Bearings-3/8 In.Clear.* Additional Experimental Conditions-None* Errors noted-ch. 19, 48 Inop.; ch. 12 No Neg.; ch. 26, 36, 39 questionable.
