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-100 Ton 60 ft Box* Truck-Barber S2C* Truck Center-46 Ft. 3 In.* Load-None* Wheel Profile-Cylindrical* Spring Group 7.D7O; 7-D7I* Snubbing-8-B432;8-B433* 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. Side bearing forces are also questionable. Individual variations of the different tests are as follows: FILE 1: Name-050302CNE001* Track-Curved* Speed-25 mph* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In. Clear.* Additional Exprimental Conditions-None* Errors noted-None***FILE 2: Name-050302CND001* Track-Curved* Speed-35 mph* Outer Gib Clarance-5/8 In.* Side Bearings-1/4 In. Clear.* Additional Experimental Conditions-None* Errors noted-None.
