Metrorail Station * - reached by Bus route 7 - gets you to  the new Metrorail's elevated Orange Line which connects to the Dadeland South Metrorail Station;  on the next stopat Earlington Heights station, you can connect to the Metrorail's Green Line, (near the intersection of SR 112, Airport Expressway & NW 22nd Avenue). For detailed information, visit:  miamidade.gov/transit/riding-metrorail.asp#1
  * NOTE: As it turned out  - the new Miami Metrorail Station was 200 feet too short for Amtrak's Miami route, which uses longer trains. Consequently it was decided to build 2 short new streets in the adjacent commercial district for vehicle detour when Amtrak's longer trains are parked (blocking Northwest 25th Street for up to 45 mins) - This project will be completed by summer 2015, whereupon the Central Station will be able to handle all means of transportation.. 
Tri-Rail* is a commuter train running along I-95 from Broward & Palm Beach Counties. Its Airport Station is presently closed and instead, the southern terminus of rail service will be the Hialeah Market Station, which will provide transport to/from Miami Airport through this station. For more information call/visit: 1-800-TRI-RAIL or tri-rail.com/bulletins.htm#list24.
   * NOTE:  By September 2015, TriRail will arrive at Miami Intermodal Center MIC - offering Tri-Rail users access directly to the  Airport and to Metrorail's Orange Line.  (It is now anticipated that 'in the not-too-distant future' TriRail is to glide into 'All Aboard' Florida's MiamiCentral.)
