As I have noted here in the past, I believe the Seaboard Air Line passes through a growing and underserved area of North Central Florida.
To note; Gainesville is a college town. I realize most princes and princesses today seem to know how to mouth the words "Dad, everybody's got one, I need a Bimmer Three..." but not all.
Ocala is one of the most attractive Metropolitan areas I know anywhere in the State - and it is constantly growing.
Down the line a bit, or some 15 miles North of Wildwood, is The Villages - a retirement community of 100,000 strong and growing. The folks there are all of train riding age - and they all came from somewhere. Simply by way of reference, on A-Day, The Villages was home to some 10000 head of beef cattle.
What I would hope Amtrak would consider is through cars (Sleeper desireable, but not completely necessary) added or cut from the Star at Jax to enable service through thir area at "people hours' The Palmetto would become what it always was - The Carolina Creeper, serving NY-Jax on its existing schedule. Tampa-Miami could be served by a Silver Palm on a schedule that existed during 1983. Only one set of equipment would be required.
Restoration of Coleman-Auburndale would be great (whose big idea was that, Nip?), but that of course means $$$$$$.
Hope they're reading @ 60 Mass.
