I'm certainly in favor of a NOL-Florida train, but even if it has through service to Chicago it will do little for Chicago-Florida travel besides eliminating the connection in DC. Besides the fact that there will be no service south of Orlando, the route takes longer than the route via DC. The travel time not including connections or station dwells is proposed to be 33:08 from CHI-JAX via New Orleans whereas using the current CL and SM route only takes 29:59, which is also interestingly 6 minutes faster than the former Floridian route. If the priority was Chicago-Florida, it would be much easier to just implement through cars between the SS and CL, which would have the added benefit of serving Miami, Tampa, and Raleigh.
