OPERATING CHARACTERISTICS OF LOCOMOTIVE AND CAR TRUCKS

In late 1971, problems were experienced by the CN on high curvature mainline subdivisions even though most of them had been recently upgraded. There were frequent changeout of outer rails on curves due to flange wear, misalignment and loss of superelevation at the spiral or entrance to curves, high spikes and rail turnover or partial turnover, and gauge widening due to the tie plates shifting and cutting into the ties, especially during the many months when the roadbed is frozen. The frequency of derailments increased simultaneously on certain subdivisions and the seriousness of the situation demanded immediate corrective action. The successful and quickly implemented program of action taken by CN is outlined in this paper.
