Finally, using Jacksonville as the terminus would render the train almost useless as Orlando is the destination for most of the passengers
True to a point, but if you time it right (overnight), you can connect with 91 and/or 97 to get them to Orlando or all the way to Miami, and same-day connections northbound on 92/98. And time the return trip right and 92 and/or 98 can get you pax from Miami/ORL, etc., to the train headed for NOL, also overnight
91/97 go thru Jax early in the morning; 98 and 92 go through in late afternoon to late evening. And JAX has a good-sized station. Also, there were quite a few transferring pax from Sunset to either 92 or 98 when it was running. We were AT Jax station several times to see that. In fact, there were more than a few times when they held up the Northbound Silver Service train so that the Sunset pax could get there and make the connection. I remember one day when 92 and 98 BOTH arrived fairly late, Sunset arrived and the various conductors and attendants had a heck of a time with Sunset pax getting on the wrong northbound Silver train (92 and 98 run very different routes north of SAV), and had to go retrieve them because somebody was a bit lax in looking at tickets.
