Split the Silver Star at Jackonsville........hmmmm.......so that would likely create a third and potentially fourth market for this train. When the Silver Star returns to a "full service" train with the delivery of new sleepers and diners etc., I think the Tampa market would be greatly strengthened with a train just to/from NYP and Tampa (with intermediate points). It's still the "long way" to get to Tampa (though the more inland route of North Carolina/South Carolina etc.) The split at Jacksonville would create intrastate travel between Jacksonville and Miami. The current Star would have to have an extra coach added for one leg or the other at Jacksonville (whether to Tampa or or Miami. The full service diner should be going to Tampa, as Miami would still get a full service diner via the Silver Meteor. Thus the Star would have to rely on an Amfleet Diner Lite operation between Jacksonville and Miami.
ANY Florida train that goes back to "splitting" in Jacksonville would be an improvement. The Tampa market has been eroded by a once a day train in either direction.
Getting the Palmetto extended to Miami - in one form or another would seem better as well. Perhaps the return of the Silver Palm.
Again, the best schedule to/from Florida was when there was a morning train, mid-day train, and evening train departing from both end points. This was achieved as late as the Warrington era with the Silver Palm leaving in the morning from NYP, the Silver Star at mid-day, and then the Silver Meteor in the evening. The opposite was equally true - only it was the Silver Palm departing Miami at about 5 pm. If it could make Jacksonville just before midnight, that would be ideal. It may be the Silver Palm that would also have to use the FEC - with also a split to Tampa or perhaps the Silver Star section from Tampa bringing passengers over but then having the Silver Palm continue up the route it currently takes closer to the Coast.
