The 3 data files on this magnetic tape include acceleration, force, and displacement measurement 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-Barber S2C* Truck Center-45 Ft. 9 In.* Load-None* Wheel Profile-New 1 in 20* Spring Group 7-D5O; 4-D5I* Snubbing-8-B432* 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-030101TSR001* Track-Med.Spd.Jtd* Speed-22 to 30 in 2 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In. Clear.* Additional Experimental Conditions-None* Errors noted-Neg.noise Ch. 42 and 45. ***FILE 2: Name-030101TSM001* Track-Med.Spd.Jtd.* Speed-15 to 45 in 5 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In. Clear.* Additional Experimental Conditions-Slight air brakes applied at 15 and 20 mph* Errors noted-Neg. noise Ch. 42 and 45 ***FILE 3: Name-030101TEM001* Track-Hi.Spd.CWR* Speed-30 to 60 in 10 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In. Clear.* Additional Experimental Conditions-None* Errors noted-Ch. 14 - 1.3V. off 0.
