I will also nominate Elyria OH. Having gone to school just down the road, Elyria would have been my station had I used LSL to commute to school from Boston. While the departure and arrivals times are abysmal (4:50am), the station itself was a big reason why I never bothered to take the train. Its unmanned, dangerous, and falling into disrepair.
Part of the reason why I think the NEC does so well is because of its station infrastructure. All of the major hubs along the NEC have great connectivity, are visually appealing (now that NYP is fixed), and have transit oriented development around them.
Nearly all other stations outside of the NEC are exactly the opposite. They are in the middle of nowhere, requiring a car to get to and from, and they offer nothing other than a place to de-train.
Chances of Amtrak moving back to the Tower are Slim and None!
And with the current crop of Anti-Rail politicians in Ohio, the chances of seeing all these additional Trains is the same!( remember the C-C-C Proposal!
This is perhaps my biggest dream for rail in this country. I loved Ohio, and I think it would see numbers similar to the NEC if Tower Terminal was revitalized and turned into a massive hub for Brightline-like service around the state. Ohio has the cities and numbers to service Intercity rail like the NEC, they just need to resurrect the once existing infrastructure.
There's a lot of younger, artsy folks in Ohio who need to travel for gigs, but have to rely on rides from friends with cars. Ohio has world class orchestras, and for those who sub in the various musical groups around the state, it would allow for them to utilize that service on one or both ways without having a car.
That said, it won't happen. sigh...
