AUTOMATIC CAR IDENTIFICATION LABEL EVALUATION AND REPAIR PLAN. PRELIMINARY REPORT

Field experience with ACI indicates there are labels on equipment that require some form of attention. These labels are identified as problem labels and include improper label applications and labels which failed to output correctly due to dirt and damage or other defects common to the operating environment. The AAR Research Center initiated and conducted a comprehensive field study in order to make an objective assessment of problem labels. This study was conducted in the Chicago Terminal District where data were accumulated on A 24-hour basis for 30 days. This is a preliminary report on the ACI label evaluation study conducted by the AAR Research Center in the Chicago Terminal District from June 28 to July 31, 1971. A total of 61.119 freight car sides were sampled and inspected. Of these, 91.43 percent were labeled. Of the labeled sides, 52,423 exhibited valid or useful labels resulting in an Overall User Value of 85.77 percent. The Overall User Value is an indication of how much good data is obtained from all of the cars. A total of 3,456 or 6.18 percent of the labels were identified as problem labels. Problem labels include label defects resulting from the operating environment and label defects due to application errors. Approximately 54 percent of the label defects resulted from the operating environment and 46 percent were due to application errors. Of the environmental defects, approximately 52 percent were due to dirt and the balance due to damage, missing labels, etc.
