HOW ONE FIRM OBTAINS LABEL QUALITY CONTROL

One method of labeling cars involves advance preparation of the Automatic Car Identification Label on a vinyl backing film or on a metal plate. The previously prepared label is later applied to the car. Computer Identics prepares labels for use by railroads. A computer is used to calculate the validity check digit and to print two label stickers for each car set of labels. After the labels are assembled, they are verified by a special test scanner connected to a computer. The computer printout verifies the actual data in the label and flags any assembly errors. The label stickers contain the word 'TOP' and the car reporting marks. People applying the labels in the field can check to be sure they have the correct car. Computer Identics also has a test site on the Penn Central with an ACI scanner, an oscilloscope, and a high speed 35 mm camera. Wheel count circuits open and close the camera shutter for each car. The camera will record any ACI signals from the car label regardless of whether or not the label is read by the ACI system. Daytime trains are spot checked by a person with a tape recorder and labeled cars are correlated with the printout from the ACI system.
