Automatic Car Identification has now been tied into the work of railroad classification yards. The Rail Terminal Management System has been developed by Kansas City Southern and ACI Systems Corporation. This system combines the ACI scanners, Abex Traffic Monitor directional wheel sensors, and mini-computers. Instant access can be had to information on the location of any car in the yard. Any car entering or leaving the yard area passes one of five ACI scanners. Four additional scanners monitor movements at strategic points in the yard. The active portion of the yard is blanketed with 252 wheel sensors to track the movement of cars. The yard has 31 classification tracks, and handles about 2,000 cars per day. Over 50 classifications are provided without reswitching of cars by making directional classifications into either end of tracks. Wheel passage over a sensor generates a pair of distinctive electrical outputs that provide unambiguous monitoring during stops or reversals. The yard data processor includes a car file with axle count by ownership and series. There are two wheel monitor processors and four label decoder processors. The ACI logic has three maps: the classification table, a sequental flow map, and a physical map of wheel sensors.
