I'll add some context to the previous discussion of why Newport News may be happy enough with the new station. I'd prefer it in Hampton myself.
The original NN station you mentioned, by the docks, is a restaurant and CSX would really not want it back there! The powers-that-be in Hampton Roads, and plenty of regular people, support facilitating industrial transportation and shipbuilding, putting up with endless streams of container trucks on highways and neighborhood roads. I'm sure the same thing goes on in Savannah - I've been caught in the truck traffic there. It's a balance, and some roads are limited by time of day. When it comes to rail, you have NS, CSX and the shortlines, serving several deep-water container ports and two large coal ports. The state gives and takes with NS and CSX, and while it has cost the taxpayers a lot, generally it has worked out with more Amtrak service, and as far as I know freight-caused delays are not bad in Virginia. Correct me if I'm wrong. The freights have opened up hundreds of miles of new rail to pax, and frequencies have increased. Yes, it cost a lot, but it's a give and take that the state has done. Amtrak advocates say the new services are paying for themselves, and they do have high ridership.
This is a big turnaround from the 1970s when the Hilltopper, the Mountaineer and the James Whitcomb Riley ran slow, delayed, and almost empty with half the passengers on legacy employee lifetime passes. Or so the story goes.
Meanwhile the freights have made improvements, like welded rail, and the rides from NPN to RVM, and NFK to PTB, are fast and smooth, noticeably better than RVR to WAS on the NEC. I could rant about RVM-RVR and why Richmond should have a single station at Broad Street Station, the Science Museum, but that ship has sailed. (Added: and I may be wrong - the track configuration there is not ideal, but there sure is plenty of room for parking and it is downtown-adjacent, with highway access. Instead all trains except the Auto Train will stop at RVR, swoop over to stop at RVM, and take a shiny new bridge over the James River to a pax-friendly alignment southward, with the plans pretty well set in stone now, whenever they do happen. The "swoop" is currently the speed of a donkey path so only NPN-bound trains go that way.)
