DESIGNING TRACK FOR MAIN STREET

摘要

Once a common practice to have freight or passenger rail service traverse paved or cobble stone streets, there are many places in America that still retain such type of infrastructure for regular railroad or light-rail service. For example, consider the once famous California Zephyr service, which still runs down a bustling street in Oakland, Calif., or consider the numerous freight spurs in the streets of the nation's small towns. Most important to point out, is the dawning (or re dawning) of the light-rail era in the United States that almost always requires some street track to ensure healthy ridership. Regarding its design and construction, there are some basic fundamentals to consider that do not normally apply to ballasted track in exclusive right-of-way.
