"As has been mentioned, there is the possibility for Amtrak to turn an SSL into a sort of 'PPC II'. Put in the Hi-Level's sofas/booths, movie theater, glass, dining. But given Amtrak's recent priorities, I don't see that is very likely."
The Amtrak FY 17-21 Five Year Service Lines Plan states as follows:
"Pacific Parlour Car Replacement FY 20-21
Modify five Cross-Country Café cars to replace 60-year old Pacific Parlour Cars on the Coast Starlight. Alternative of overhaul existing cars will be evaluated."
Well, the "evaluation" has apparently been completed, and we now know the result of the evaluation. There is no indication that the primary alternative of modifying five Cross-Country Cafes is not still in the five year plan.
