Well, and I suspect that a Cardinal/Star-esque meal offering (the Cryovac meals) would be a good move. Aside from the stop at WAS it isn't like there's generally time to grab a bite from a station, and someone going NYP-CHS or WAS-SAV might well have a reason to want at least one meal that's a bit more than a microwaved burger and some cup-o-noodles.Dining car service on the Palmetto, in particular, is an interesting concept as the train covers three meal periods - same as the southbound Silver Meteor if you exclude dinner prior to the Miami arrival (does #97 even serve dinner if on time into Miami?). People tend to talk about full dining cars (or lack thereof) on the overnight trains, but you don't need or want meals while you are sleeping; You want them during the day - breakfast, lunch, and dinner - while you are awake.Ten car NE regionals! (That includes the Vermonter.)
More seats would drop NEC fares and maybe get some diesel-belching Bolt buses and Megabuses off of I 95.
More NEC trains with baggage car service.
Dining car service on the Palmetto, the Carolinian, the Pennsylvanian, and some selected. VA-DC-Boston services. Cafe cars on the Keystones and Albany trains.
Hourly corridor service outside the NEC.
Anything that would allow rail to have significant market share in its corridor, similar to what's in the NE.
