Outside of NYP-WAS, I don't think there's anywhere in the NE that Amtrak would seriously consider axing food service entirely (and even on that stretch, that's a 4-hour run in most cases...which can be a long time if you don't have at least a decent soda machine). With that said, if there were trains selling out BC (or close to it), wouldn't having 78 BC seats make sense (i.e. a dedicated BC car and a split car)? Also, moving food service to one end of the car and having a 48-seat car (16 2-1 rows instead of 20) might also make sense in some cases if BC wasn't close to selling out. Making the car coach could also work, too...again, depending on demand.
I was not suggesting removing the café car from trains. Amtrak has - or did have - an excess number of café cars in the Amfleet Is when they are now running just one café car in a typical consist. Amtrak is converting 20 Amfleet I café cars to all coach (revenue) cars with the stimulus funding. Checking the On Track On-line Amtrak fleet info, 19 out of the 20 have been converted and released to the fleet as of September 1. Perhaps Amtrak now has the balance of coach cars, all business class cars, all dinettes, and club-dinettes they want - while trying to keep them all running until Amfleet I replacements show up.
Mixing 2x1 business class seating with a 60 2x2 business class car could lead to some grumpy passengers wondering, hey, why did I end up in the 2x2 seats? :lol:
