EDIT; Since the whole project was billed and funded as “State of Good Repair” a lot of my recent hopes and comments are vastly overblown. The typical results of state a good repair work our schedule reliability.
Separately, Vertical curves are a thing (I Googled and learned about crests and troughs)
Now that we understand that “quick hits” on horizontal curves is like some mix of superelevation (banking) and straightening , I wis we had more details on what kind of noticeable improvements could/will be made.
SOGR on superelevated curves usually involves (1) ballast touch-ups and (2) replacing the lower rail because slow/freight trains have worn against it from the tilt
But are there curves yet to be straightened? I get that some curves are curvy because they were laid along a curvy centerline because they anticipated “freight” sidings that are either long gone or never existed
Now that we know the track will never be constrained between sidings and the ROW boundary, it’s free to drift within the ROW in the interests of being straightened. Was that all done 2011-2018?
