Perhaps a bit too far in the fantasy side, but I don't intend this to be an all or nothing scenario. The following is what I would LIKE to see, not what I EXPECT to see.
Restored Desert Wind
Restored North Coast Limited
Restored Broadway Limited/3 rivers, Via route of Capitol west of Pittsburgh. This takes the Lake Shore's slots. The Lake Shore needs to be earlier EB and later WB.
Second Starlight, Third Silver Service.
If it can be done, The Floridian. If not, perhaps the third Silver could be in actuality a continuation of the Capitol Limited allowing through ticketing.
Of course, this all needs a more friendly congress than today.
Virginia: Richmond Main Street really needs to be the south end of the NEC. Getting an electrified higher speed right of way will be hard, but is certainly justifiable. Also, connecting RVM to the Atlantic coast service would really help Richmond. Other than that, Boost Lynchburg/Roanoke as well as Norfolk. Friendly state government makes this one a lot more possible.
North Carolina: Eventually add another Piedmont or two. Extend them east as well. Unfriendly state government, but might be popular enough to happen anyway.
Pennsylvania: Pittsburgh needs at least 2 TPD. Friendly state government. This should happen.
PA NY NJ: I'd love to see new NY-Scranton- Southern Tier corridor. Probably would have to wait on friendlier state governments in both NY and NJ.
New York: Additional service west of Albany.
CT/MA: Restore at least one daily through train on the inland route. Should have never been cut.
Overall: More evening service. 9PM should be the absolute earliest for a last train anywhere within Richmond, Harrisburg, Albany, Springfield, Boston ring around NY.
Michigan: Make the holiday schedule the normal one! I think the state would support this. Might actually happen when all the current projects in ROW and rolling stock come along further. Restore the international!
Illinois: Essentially do what is planned! I am still cautiously hopeful for Quad Cities, although the Black Hawk has done little but disappoint. Additional frequencies of the other corridors too. Not sure how the state is going to act on this one.
3Cs a must. Day trains CHI-Cleveland and CHI-Cincinnati are no brainers. Requires friendlier governments in both states. (i.e. Can't really start doing anything for at least 3 years here.)
Wisconsin: Madison at the very least needs to happen. Again, nothing at all for the next 3 years.
West: The state plans of the west coast states all seem to be in the right idea. On top of that, a LA-LV corridor is needed. Perhaps LA-Phoenix/Tucson too. These are Large investments for sure. Perhaps also Talgo service along the routes of the Empire Builder in WA/OR.
