... You could fill the CAF options with BC only cars. Add one to each single level car train. That way capacity is actually increased.
YES! More capacity of every type of Viewliner -- business class, sleepers, bag dorms, baggage, probably even diners.
A Business Class Viewliner-2 could be a nice upgrade just by being newer, with higher windows and ceilings, better HVAC, more outlets, better WiFi..
Make them all 2-1 seating and offer First Class standards. Not to call it "First Class" because bean counters don't like to see those words on your expense account. But Business Class is fine, or Business Premium or Business Plus. Perhaps put the upscale car in the front of the train, behind the baggage car but ahead of the sleepers (to put more distance between the train whistle and those trying to sleep).
Of course, coach class capacity would be increased a bit as the existing Business Class cars reverted to the coach fleet.
Yeah, I know Amtrak is trying to reduce the number of different types of cars. Good luck with that. When it offers sleepers you might get a Viewliner or a Viewliner--2, with or without the potty in the roomette, until the original type are all upgraded? But I digress.
A "Business Plus" car with 2-1 seating could create a kind of 'Coach Plus' sleeper, a more spacious and comfortable place to overnight than coach, but much cheaper than a roomette. It might draw customers from sleeping class (looking to save money) and from coach class (looking for better but affordable space), thereby creating more capacity in both roomettes and coach seating.
CAF could handle the job. The delays with the diners have been so stressful because the heritage diners are done and their replacement is urgent. And CAF seems to be doing better lately. In two or three years, when the last of the diners and the bag-dorms and sleepers are finished, adding another 25 Business Class cars should be quite doable.
Some will say, get the business class cars out of the coming order for hundreds of coaches and lounge cars. And that multi-Billion order will be funded when? Delivered when? I think the order is at least one election away, maybe two, then time from order to delivery. We could get more cars from CAF around the same time, or sooner.
