Light rail or light rail transit (LRT) is a form of urban rail public transportation that generally has a lower capacity and lower speed than heavy rail and metro systems, but higher capacity and higher speed than traditional street-running tram systems. The term is typically used to refer to rail systems with rapid transit-style features that usually use electric rail cars operating mostly in private rights-of-way separated from other traffic but sometimes, if necessary, mixed with other traffic in city streets. If this is the case, then under the law of many countries such systems are legally tramways, although the vehicles which run on them are sometimes designated "supertrams". Modern light rail technology is flexible and adaptable, and whether any given system is considered a true rapid transit system or not depends on its characteristics.
A people mover or automated people mover (APM) is a fully automated, grade-separated mass transit system.
The term is generally used only to describe systems serving relatively small areas such as airports, downtown districts or theme parks, but is sometimes applied to considerably more complex automated systems.
The term was originally applied to three different systems, developed roughly at the same time. One was Skybus, an automated mass transit system prototyped by the Westinghouse Electric Corporation beginning in 1964. The second, alternately called the People Mover and Minirail, opened in Montreal at Expo 67. Finally the last, called PeopleMover or Goodyear PeopleMover, was an attraction sponsored by the Goodyear Tire and Rubber Company which opened at Disneyland in 1967. Now, however, the term "people mover" is generic, and may use technologies such as monorail, duorail, automated guideway transit or maglev. Propulsion may involve conventional on-board electric motors, linear motors or cable traction.
