A measure of success

摘要

During the past few years, North American railroads have bolstered their track structure by monitoring rail profiles, preventing rail wear and maintaining track gage strength. They've also altered a few main-tenance-of-way (MOW) processes that are helping to keep track in top form.rn"Good grinding and lubrication practices are reducing rolling contact fatigue," says Gary Wolf, president of Rail Sciences Inc., which provides track assessment and audit services, and measures track geometry, rail profile and gage strength for freight and passenger railroads.
