Tri-rail's web site is here:
http://www.tri-rail.com/ They have pretty useful information there. Using the Miami Airport Station of Tri-Rail, their shuttle bus to/from the airport is only a six-minute run by the bus each way, so it really must be close. We have used Tri-Rail to get around So. Fla after getting down there by Amtrak from Winter Park (Orlando area), and it's a nice, reliable system. You can also track their trains (real-time) on their web site, shown as positions and train numbers on a trackage map, and it tells you how close to schedule each is running and it's current speed., all of which is kinda neat. If you are looking to fly out of Miami, check out available flights from the Ft. Lauderdale airport, they usually have cheaper fares but just as many flights, or more, as from MIA. They are cheaper from there because that airport has MUCH lower fees charged to the airlines per passenger and per landing, than MIA does. You can get to that airport by a short-run (takes approx 15-20 minutes, or about 9-14 minutes longer than the one to MIA) shuttle bus from the nearby Tri-Rail station also. The Tri-Rail site has all of those shuttle bus schedules and of course the Tri-Rail train schedules as well, on their web site.
I noticed that error on the timetable also, showing the Carolinian miraculously leaving Miami. The printed version they had on the train, and at the WPK station, had the error.
It is an interesting experience running backwards on 91/92 into Tampa. It feels like a good bit longer than a half-mile, though, I would guess at least two or three miles. Quite a few crossings. You go by all of Ybor City backwards on the way in and frontwards on the way out.
Sunset Limited does the same thing (but not into Tampa, of course!), having to back into (or out of) the Jacksonville, FL station as it changes from North-South running South of Jax to East-West running West of Jax. It also does that at Orlando, running though a Wye South of the Orlando station by a few miles, but there are no passengers on board when it does that. Inbound it drops off all the pax before heading south to the wye, and outbound either the entire train goes straight to the wye before stopping at the station to p/u the pax, or the engine pulls the train backwards to the Orlando Station, drops off the consist, and then the Engine heads So., does the wye, and then comes back and runs around the train on double track, backs down onto the train and then off they go.
