One issue that's very minor is just what exactly to call a train that goes all the way to Roanoke? Is it still a Northeast Regional? Because if Amtrak's not careful, they'll have a "Northeast Regional" going all the way to LAX!
Seriously now, it looks like turning facilities in RNK aren't that bad judging from Google Maps (what would we do without it?). There seems to be an in-service WYE track SE of the Station that abuts the Roanoke shops. Of course, such a move would require tying up the main tracks for a while which I'm not sure NS would be thrilled about. Another solution is to shove the Amcans somewhere, then turn the P42 (only 1 right?) on the Roanoke shop's turntable then have to run around the train and couple back up. Another is to use a Cabbage or Metroliner cab car or one of those AEM-7 cab cars once the new electrics arrive and just push-pull the train.
[EDIT]: Another bonus of RNK is appears to already have a platform!

Ah, the naming dilemma. I'm still in favor of something like the "Old Dominion" or "Hilltopper," to be honest. But unfortunately, politics get involved in things like this (hence "Lynchburger" was no joke) and every town wants the darned thing named after them specifically; that's why we've got Northeast Regional. I think Amtrak can get away with taking the NE Regional name to Roanoke, but no further. West of that, it becomes a joke (albeit a fantastic AGR redemption). As I said before, I think we'll get a corridor name for this route once we have multiple daily frequencies, similar to the Cascades.
The Y southeast of the station is the logical place to turn the train. Figuring out where to store the train overnight, whether to Y, or to engine rotate, or to cab car the service is all part of negotiations with NS, so it's all very much just speculation on our part right now.
The platform at Roanoke can work (and did work on the excursions this past November), but there is no station-side platform, which I'm guessing will be required. It's just an island platform inbetween tracks. Remember, the N&W Station (now the Link Museum) used to have a catwalk across the tracks with stairs leading down to the island platform. That catwalk is now long gone, and the train may require a platform station-side. Alternatively, an escalator and elevator could be added to the Hotel Roanoke bridge, which crosses the track platform, but access to that bridge is a good distance from the Link Museum.
Anyway, I digress. Speculation is dangerous!
