Metrorail, colloquially called the Metro, is the heavy rail rapid transit system of Miami, Florida, United States, serving the Greater Miami area. Metrorail is operated by Miami-Dade Transit (MDT), a departmental agency of Miami-Dade County. Opened in 1984, it is Florida’s only rapid transit metro system, and is currently composed of two lines of 23 stations on of standard gauge track. Metrorail serves the urban core of Miami, connecting the urban centers of Miami International Airport, the Civic Center, Downtown Miami, and Brickell with the northern developed neighborhoods of Hialeah and Medley to the northwest, and to suburban The Roads, Coconut Grove, Coral Gables, and South Miami, ending at urban Dadeland in Kendall. Metrorail connects to the Metromover in Downtown, which provides metro service to the entirety of Downtown and Brickell. Additionally, it connects to South Florida’s commuter rail system at Tri-Rail Station. Together with Metromover, the system has seen steady ridership growth per annum, with an average of 105,500 daily passengers in 2013. In 2012, Metrorail opened its 23rd station, Miami Central Station, at Miami International Airport (MIA), opening a 16-station newly created Orange Line between the MIA and Dadeland South stations. The new line is expected to increase ridership significantly, adding millions of riders per year, and allowing residents and visitors alike direct access from the MIA to Downtown Miami, and greater connectivity between various modes of transit throughout Miami-Dade County. Central Station provides direct service to Amtrak inter-city rail services, Tri-Rail commuter rail, Greyhound Lines intercity bus, and the Rental Car Center.
