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-Full* Wheel Profile-New 1 in 20* Spring Group 7-D5 O; 6-D5 I* Snubbing-8-9031* Snubber Augmentation-None* Centerplate Friction-Steel-Moly* Additional Experimental Devices or Conditions-Constant contact side bearings* 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-040406TWA001* Track-Hi.Spd.Jtd.* Speed-30 to 70 in 10 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-7500 lb. Preload* Additional Experimental Conditions-None* Errors noted-None ***FILE 2: Name-040404TWA001* Track-Hi.Spd.Jtd.* Speed-30 to 79 in 10 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-2500 lb. Preload* Additional Experimental Conditions-None* Errors noted-None ***FILE 3: Name-040405TWA001* Track-Hi.Spd.Jtd.* Speed-30 to 79 in 10 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-5000 lb. Preload* Additional Experimental Conditions-None* Errors noted-ch. 40 went Bad during test.
