Killing one train to somehow benefit another is not a good strategy.
No one ever said it was a good strategy, the argument is whether or not it is a viable one or not, the argument is whether or not the service you want to start/restart is better/more important than the service you want to eliminate/get rid of. Of course we want to keep all our trains and add if we had the money and equipment but of course we don't (or go find the money and we can end this argument once and for all).
Not sure if per federal law, that a New Orleans to Jacksonville train would have to be state supported, or if could be federally funded? Forget the distance, but maybe I'll look later on the Amtrak timetable history website to see what that mileage distance was. Have to finish packing for a 5 day trip I'm doing, so can't look that up now.
619 miles, not enough,
NOL-ORL would be 770 and would make enough and would make more sense since I believe the service facilities are closer and it gives direct access to the Florida attractions. That's probably why it makes more sense just to extend the CONO and offer the one seat ride from CHI-ORL and one less transfer from California.
