Canadian Pacific (CP) has taken a systems approach to minimizing the stress state and maximizing velocity in high-tonnage, heavy haul western Canada mainline operations. Recognizing the interaction between wheel-rail contact mechanics, train handling, and track geometry, CP has tested and implemented a number of advanced technologies that leverage current knowledge, systems, products, and equipment in each of these areas. This includes implementation of distributed locomotive power configurations based on sophisticated track/train interaction modelling, as well as the state-of-the-art top of rail and gauge face friction control. Together, these technologies have resulted in reductions in damaging lateral forces, rail wear, and fastening system fatigue, as well as increases in velocity and network capacity. This article presents the theory, implementation, and verification of distributed power, fine tuning curve superelevation and friction control technologies within the practical operating conditions of British Columbia.
