| 摘要： | SkyTrain, Vancouver, B.C.,'s iconic rail transit system, is a system in motion. Since the opening of the original Expo Line, named and timed to coincide with the 1986 World Exposition on Transportation and Communication (Expo,86), Sky Train, which moves more than 115 million commuters per year pre-COVID-19, has been a story of expansion and growth, and the growing pains that come with it. A modern system when it opened in 1986, unforeseen wheel and rail wear issues started to appear shortly after startup. A few years of trial and error and hard-won development of innovative rail profile grinding and wheel re-truing programs, along with the introduction of newly developed friction modifiers, normalized wear and stabilized the system. All was good. Unfortunately, as often happens on transit systems, competing priorities and cost reductions led to a lapse in SkyTrain's focus on rail maintenance practices. |
