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-New 1 in 20* Spring Group 7-D5 O; 6-D5 I* Friction-Steel-Steel* Additional Experimental Devices or Conditions-Adapter Clearance is 0; Longitudinal pedestal controls under Axels* 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-040106TEM002* 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. 35 Bad; Ch. 18 -2.7v off 0; Speed has neg spikes ***FILE 2: Name-040106TEH002* Track-Ho.Spd.CWR* Speed-70 and 79 mph* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In. Clear* Additional Experimental Conditions-None* Errors noted-None ***FILE 3: Name-040106TWA002* Track-Hi.Spd.Jtd.* Speed-30 to 79 in 10 mph steps* Outer Gib Clearance-5/8 In.* Side Bearings-1/4 In. Clear* Additional Experimental Conditions-None* Errors noted-None.
