I think it safe assumption to note that Amtrak isn't competing for anything in the Florida market. It's hard to believe that "two a day" remain down there as the "one a day" end point model was demonstrated during the "tri-weekly" period, of which there is no assurance that the last of that has been seen.
Now so far as Brightline, the "Real Estate play" outlined in previous posts cannot be ignored. It just might be the salvation for an initiative that never once "made numbers" during its '18-'20 "Disneyland ride" trial run. However, terminating at McCoy Field, there are limitations on the commercial development around the perimeter of such. Now regarding when it commences to provide real transportation between population centers, we shall see. To my amazement, this appears to be a go; but then there are some "fat and sassy" accredited investors laughing all the way to the bank. 8% Federal Tax free is not a bad haul; State tax free as well as most of them if they reside in income tax free Florida. Also bet these investors have enough pull to have "Tallabux" flowing should the venture flop. Such a bailout would be the State buys up the bonds from the investors, say @ 95 (par would look too much what it is - a bailout) and takes over Brightline's operation. Lest we forget, Florida is quite willing to support passenger rail - just so long as it isn't Amtrak!
Now I know and accept my earlier skepticism regarding AAF/Brightline (let's skip the Virgin Rail part) that it was a ploy to sell the FEC to the State proved mistaken, and that during the Disneyland Ride period, I had eight very enjoyable joyrides on it. So far as what's ahead
"Que Sera Sera".
