The Miami Metrorail opened on May 20, 1984. It is a completely above ground line, with all but a few sections being elevated. The Metrorail now has 23 stations, including connections to the Metromover system, Tri-Rail, and Miami International Airport. The 136 rail cars on the line were manufactured by Budd as part of a joint order between Miami-Dade Transit and the Maryland Department of Transportation.
