I agree with Noel. In fact, this is even more true on weekends when the Orange line (Metrorail to Miami Airport) runs twice as frequent as the Green line (Metrorail to Hialeah). A couple weekends ago, I took Tri-Rail to Miami and transferred to Metrorail at the Airport station. I was already halfway to downtown before the next Green line train stopped at the Tri-Rail transfer station.
Note you can track Metrorail trains on Miami Dade transit's website- http://www.miamidade.gov/transit/traint ... lected=MIA
