light rail transit, system of railways usually powered by overhead electrical wires and used for medium-capacity local transportation in metropolitan areas. Light rail vehicles (LRVs) are a technological outgrowth of streetcars (trams). Light rail transit lines are more segregated from street traffic than are tramways (particularly in congested urban areas) but less so than are rapid transit (heavy rail) lines. See mass transit.
