Hopefully, if the Viewliner IIs pass testing without major problems, they can accelerate the production. They really seem to be behind schedule. (wasn't the order placed in 2010?)
I just hope that the delays don't come back to bite them. I wonder what the next steps will be after the current Viewliner II order is completed. If I remember correctly, the Amfleets are getting pretty old too. Would they order Viewliner II coaches, or a new design (anything but brand new versions of the current Amfleet design; I can't think of anyone who thinks that those cars are any fun to ride it)? I have a feeling though that the Amfleets are a pretty low priority, and will be used until they fall apart. Amtrak's next major project seems to be an Acela replacement.
According to the last version of Amtrak's "Fleet Strategy Plan", which was issued in 2012:
- the top priority in rolling stock was the things currently on order: the new Viewliners (to replace Heritage cars, and because extra Viewliner sleeper space pays for itself)
- the next priority was the Acela IIs (because extra Acela space also pays for itself, and they'll be substantially longer than the existing Acelas). The existing Acelas will probably stay in service rather than being retired immediately.
- the next priority was Amfleet II replacement, because they have higher mileage than Amfleet Is, are the second-oldest, and there weren't enough of them to start with
- followed by Amfleet I replacement, because they are the oldest (after the Heritage cars)
In earlier versions of the fleet strategy plan, Amfleet I replacement came before Amfleet II replacement (because Amfleet Is are older).
Superliners are way back in the queue, there's no doubt about that; Amtrak clearly considers Amfleet replacement to be a much higher priority.
The Fleet Strategy plan listed priorities separately for rolling stock and for locomotives, so it's not clear whether "Amfleet II replacement" is a higher priority than "P42 replacement". I'd personally guess that P42 replacement is a higher priority, but it's just a guess.
Amtrak claimed it would issue a new fleet strategy plan yearly, but obviously they didn't.
