The Los Angeles County Metropolitan Transportation Authority (Metro) operates six rail lines as part of its Metro Rail system. This system includes four light rail lines and two rapid transit lines. The agency owns, operates, and maintains a fleet of 439 rail vehicles.[1]

Metro operates two main types of rail vehicles: light rail and rapid transit. Metro's light rail vehicles, used on the A, C, E, and K lines, are 87-foot (26.52 m) articulated double-ended vehicles, powered by overhead lines, which typically run in two or three vehicle consists. Metro's rapid transit vehicles, used on the B and D lines, are 75-foot (22.86 m) electric multiple unit, married-pair cars, powered by electrified third rail, that typically run in four or six-car consists.

Metro plans to build three new rail facilities over the next few years.

• A new facility will be built in the San Fernando Valley west of Van Nuys Boulevard south of the Metrolink tracks as part of the planned East San Fernando Valley Light Rail Transit Project.
• A new facility is being studied for either Bellflower or Paramount to support operations on the Southeast Gateway Line.
• A new facility will be built in Montebello, bound by Flotilla Street to the north, Yates Avenue to the west, South Vail Avenue to the east, and Washington Boulevard to the south to serve the Eastside Transit Corridor Phase 2 project, which extends the E Line to the intersection between Washington Boulevard and South Greenwood Avenue.
