This new line provides for convenient transportation to to MIA (Miami International Airport). This makes for ideal transportation for anyone undergoing an International mover from Miami. Not only ideal for them but also for people who commute frequently. The down side to this new metro rail line is that they had to take train cars from other lines to make a train, which is where the complaints are coming from. For example one train was shortened from six train cars to only four and the traffic on them as remained the same, if not increased. Many have said that the train cars were not overfilled, just full.
