CP Rail will use Automatic Car Identification in three areas: as an important subsystem in a new computerized yard, as an integral part of a coupled weigh in motion scale for unit train service, and as an integral part of interchange procedures. The CP Rail yard at Calgary will be controlled by a digital computer. Ten ACI systems will form an important part of the operation. One ACI scanner will be on the hump, and the other nine will be located at strategic points to scan arrivals, departures, and switching moves. The coupled weigh in motion operation uses an electronic scale, a computer, and an ACI scanner. The empty unit train crosses the scale and passes the scanner, than proceeds through the loading silos and around a loop, and finally passes the scale and scanner in the opposite directions as it departs. The system determines accurate weights for each car in the unit train and automatically records the weights for revenue billing. The interchange application is a joint venture with CN, with the ACI recording all movements in interchange at the test location.
