Metrorail runs from the northwest in Medley through Hialeah, into the city of Miami, the downtown area, through Coral Gables and South Miami, and ending in southwest Miami-Dade at Dadeland Mall.
There are 23 accessible Metrorail stations, one about every 1.25 mi (2.012 km).
Metrorail connects to the Metromover system at Government Center and Brickell stations and to South Florida's Tri-Rail suburban commuter rail system at the Tri-Rail station (see below).

Since completion of the Airport Link in 2012, Metrorail increased its service frequency to peak headways of three and a half to five minutes on the shared portion of the line from Dadeland South to Earlington Heights.

Along with the Metrorail system, the tracks are mostly elevated.
The three sections that are not are under I-95 between Vizcaya and Brickell stations, under I-95 just east of Culmer station, and the northern end of the line from just east of the Palmetto Expressway heading west into the Palmetto station and tail track.
In each of these cases, the tracks ride on the ground level for a brief amount of time.
The platform at each Metrorail station is long enough to accommodate six-car-long trains; the Dadeland North, Earlington Heights, and Government Center station platforms are long enough to accommodate eight-car-long trains.
In-service trains are usually either four or six cars long; in the evening it is not uncommon for Miami-Dade Transit to link two out-of-service trains together before returning them to Lehman Yard.
Trains are stored at the Lehman Yard just west of Okeechobee station.
There are extra tracks and a new test track, known as the Lehman Center Test Track, built at the Lehman Yard.
