EFFECT OF HEAVY AXLE LOADS ON RAIL AND TIES

The Quebec North Shore and Labrador Railway was built in 1953 to handle iron ore from mines 350 miles north of the St. Lawrence River. Trains of up to 280 cars with five locomotive units are operated. This presentation reports the maintenance experience on track which carries up to 50 million net tons annually, and has handled almost 700 million gross tons since opening. Among the findings: line, surface and gauge must be maintained even on tangent track; corrugated rail develops quickly on grades and curves and must be countered promptly; joint bars must be kept tight and rail ends restored; oilers are all-important on curves.
