Canadian Pacific has modernized the old Alyth Yard to the standards of today. The new yard has a sustainable throughput of 3,000 cars per day and incorporates the greatest number of automation features to date in one yard. Located at the junction of four main lines, Alyth Yard is the keystone of CP operations in the west. The problem is to keep everyone informed of factors affecting their work, and the objective is to supply each yard supervisor with the information he needs. Two Honeywell DDP-516 process control computers with associated peripherals provide process control, data processing, and back-up protection. The punched card format used is the same as that at the central computer system in Montreal. Seven cathode ray tubes with keyboards are used for input-output devices, and printers are used for hard copy. Complete data on every car in the yard is available in the computers. Ten Automatic Car Identification scanners will be used, eight at yard entrances, one at an interchange, and one on the hump approach track. Computer enhancement of the ACI data will be performed.
