Four articles describe the operation and maintenance of this Canadian heavy-haul railway. Built 20 years ago, the 276-mile line has experienced steady traffic growth in iron ore and has refined preventive maintenance and upgraded cars, locomotive and track. Its unit trains are handled by 2-man crews and normally involve remotely-controlled pusher units operating through a region with much snow and sub-zero temperatures. Train performance is closely monitored to achieve maximum effectiveness from 2000 cars and 54 locomotives producing 10 billion gross ton miles annually. Cartier is now converting to continuous welded rail, bridges are being improved with ballast decks, and rail grinder now controls corrugations. Cars and locomotives are cycled through the maintenance shop on precise schedule. Centralized traffic control and radio have been used from beginning; original CTC is now being supplemented by a new microprocessor which stores information on track occupancy and identifies trains. Computer is also used to process other operating information.
