I was really expecting that coach access to the diner would be restored with community seating.
Since it isn't, I think casual access to the diner by coach passengers is a thing of the past. I know Amtrak is thinking about offering pre paid, pre reserved plans for coach passengers for diner access, but I am afraid that the days of deciding, on the spur of the moment, what the heck, I am sick of the cafe nuke-burger, let's have lunch in the diner look to be gone.
I think it's a shame. I also think it is a mistake. It is handing the Micas of the future a club to beat Amtrak with.
The railroads never restricted coach access to the diner despite it being primarily intended for Pullman passengers.
