I spoke with someone very close to the situation, reality, no one (even at Amtrak or FEC) knows how it will pan out in the end. There's been speculation ranging from the Palmetto returning to Florida (probably running the Meteor route with the Meteor going to FEC), to the Sunset coming back and running FEC to Miami, to splitting the train. No one knows anything. The only true definite at this point appears to be that there will be a dedicated fleet of motors that will be captive between for FEC service. Since FEC runs its own cab signal system that the Amtrak cab signal system isn't compliant with there will be dedicated motors for this service similar to Michigan service. You may see this manifest in one of two forms. Either there will be a WAS based fleet that will only be assigned to the FEC trains or there will be an additional power change at JAX. It may end up being easier in the end to do a power change at JAX since this is a refueling location anyway. Also, don't forget while the FEC route is only slightly shorter mileage wise, it is MUCH faster. There is a lot of slow going from JAX-ORL with a lot of curves in there. FEC is very straight, and very fast. It looks highly likely it will happen this time. But like I say every time, I'll believe it when I see it.
