Light rail is a mode of rail-based transport, usually urban in nature. When compared to heavy rail systems like commuter rail or rapid transit (subway), light rail systems are typically designed to carry fewer passengers and are capable of operating in mixed traffic or on routes that are not entirely grade-separated. Systems typically take one of four forms: the "first-generation" legacy systems, the "second-generation" modern light rail systems, streetcars, and hybrid rail systems. All of the systems use similar technologies, and some systems blur the lines between the different forms.
The United States is served by a wide array of public transportation, including various forms of bus, rail, ferry, and sometimes, airline services. Most public transit systems are in urban areas with enough density and public demand to require public transportation; most US cities have some form of public transit. In more auto-centric suburban localities, public transit is generally less frequent and less common. Most public transit services in the United States are either national, regional/commuter, or local.
