What Is Light Rail?

Light rail is a form of rapid transit that is an intermediate step between streetcars and heavy rail. Light rail systems are generally powered by electricity provided through overhead wires, operate on a separate right-of-way that is not grade-separated from traffic, and run one-, two- or three-car trains.
