Illinois Central has provided on-line, real-time control for their intermodal exchange (IMX) piggyback facility. Control is obtained by a digital computer fed by five Automatic Car Identification scanners. Two ACI scanners check trains in and out, and three scanners are located at gates on the road entrance/exit points to check tractors and trailers. Teleprinters and cathode ray tubes provide for input/output. The control system controls twelve basic functions: trailer and flat car inventory, inbound shuttle and pickup, delivery, trailer reservation, patron release and pickup, inbound gate, parking, programming trailer loading on flat cars, cartage, trailer repair and credit reclaim, detention and yard storage, and performance measurements. Conventional automatic parking lot gates are used to control entry/exit of vehicles by road. About 300 trailers per day are handled through IMX. The control system has been a big aid to keeping outbound piggyback trains on time.
