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-70TonMReefer* Truck-ASF Ride Control* Truck Center-45Ft.9In.* Load-None* Wheel Profile-Cylindrical* Spring Group 7-D5O;6-D5I* 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-050101CNE001* Track-Curved*Speed-25 mph* Outer Gib Clearance-5/8 In.* Side Bearings-1/4In.Clear.* Additional Experimental Conditions-None* Errors noted-Ch.30-0.3; ch.41 and 0.4;ch.44-0.4 volts off 0 ***FILE 2: Name-050101CNO001* Track-Curved* Speed-35 mph* Outer Gib Clearance-5/8In.* Side Bearings-1/4 In.Clear.* Additional Experimental Conditions-None* Errors noted-Ch. 30-0.3 v. off 0.
