One thing that struck me was how nice the lounges on these trains are (no revenue seating anywhere in the car, not sure what was downstairs) and what a waste given everybody went to the car, got their food from the cafe, and took it back to their seat, or in most cases the tables in the coach cars.
Seems to me it would make more sense to put Surfliner Cafe/Coaches on these trains with the little lounge tables downstairs and seating upstairs and send these roomier Capitol lounges to trains like the CONO and routes that really need more lounge space.
