My question was not really about "southeast Florida" or "intermediate stations" I was specifically referring to those who would ride from one end to the other in a single seat trip.
I suspect there could
potentially be quite a few. I'm guessing that the time frame from Miami to Tampa on Brightline would be around 4 1/2 to 5 hours. I could be way wrong - I'm not quoting anything they may have posted.
That compared to about 4:15 by car (no stops) according to Google Maps. So for an extra 15-45 minutes to not have to deal with traffic or driving? I would consider value in that.
My bigger concern is comfort. I planned to ride Brightline from WPB to MIA a few months ago. I was SO uncomfortable that I turned around at FLL. I cannot imagine riding for over an hour in those seats. The saving grace is you can get up and walk around. That's nice.
So then there's the price point. If the plan currently is to charge between $50-$75 from MIA to MCO, then I would suspect probably close to $100 from MIA to TPA. Google shows flights from MIA to TPA from $110, and only a little over an hour of flight time. Yes, you need to consider the ancillary time associated with TSA, etc. I don't consider the "last mile" because you need that to/from an airport just like you do from a train station. Not everyone needs to go downtown. I think I would rather sit in a seat on Spirit for 1 hour than a Brightline seat for up to 5 hours.
So then the final question is - are more people willing to take the train, once an hour, 365 days a year OVER flying or driving? When all paths are similar, I DON'T see a huge market share grab with the end-to-end traveler.
Oh a bit of an aside, and for the sake of equal opportunity transports, RedCoach offers bus service from MIA to downtown Tampa for $25/coach, $60/business and schedules the trip for 5 hours and 10 minutes.
