This questions requires a rather involved answer for the benefit of those
on here who may not be familiar with this area.
Tri-Rail runs over state owned former Seaboard Air Line tracks which
generally speaking run somewhat west of the original downtown areas of
the various cities that it passes through and connects.
At the south end of this line, there is a connection at Metro Rail transfer
station with the Metro Rail system which connects Hialeah with the central
part of Miami and then continues south to the Dadeland Mall in a part of
Kendall.
The above Metro-Rail line does not really pass through the middle of the
city of Miami which is even further east but rather stops in the downtown
area at the court house area and sight of the old Florida East Coast
passenger station at a station named "Government Center", just like
Boston, heh. There is also a near-by station just to the south named
Brickell.
At both Government Center and Brickell stations another system called
Metro Mover connects with Metro Rail and provides automated single cars
(crewless) operation with a fixed guideway and rubber tires over a system
of maybe three miles long with stations very close together and covering
the entire downtown area including Bayfront, American Airlines Arena and
just about everything else too. These automated cars run over two lines
one to Financial Center the other to School Board station. Each line covers an inner loop as well.
There is no cost to ride this great system, all stations are elevated and have escalators as well as stairs and go up and down grades, cross a very
high bridge over the Miami River and go right through some buildings.
I strongly recommend to anyone in the area to RIDE IT.
