To reach Miami International Airport (MIA) directly via rail in 2026, you should take the Metrorail Orange Line. This dedicated line terminates at the Miami Intermodal Center (MIC), which is the airport's massive transportation hub. Once you arrive at the MIC station, you simply transfer to the MIA Mover, a free, automated 24-hour people mover that whisks passengers directly into the airport terminals in about four minutes. For those traveling from outside the immediate city, Tri-Rail (the regional commuter rail) and Amtrak also serve the Miami Airport Station at the MIC. Additionally, Brightline, the high-speed private rail service, offers "Brightline+" shuttle connections from its MiamiCentral downtown station directly to the airport. It is important to note that while the Orange Line is the primary direct route, travelers on the Metrorail Green Line must transfer to an Orange Line train at the Earlington Heights station to complete their journey to the airport.
