The funny thing is, I like these older trains that Amtrak runs as regionals better than the newer (and out of service at the moment) Acela trains. Why? They aren't that much slower, and they have much nicer Cafe cars. The not so well kept secret of the old MetroLiners was that the cafe cars were always in high demand. They have nice, large tables that seat four, and you can set up a PC and a mouse easily and comfortably. No hassling with a wobbly tray table - you can work on your laptop during the entire ride.
Not the case on the new Acelas, or even the updated regionals. There, the Cafe cars are mostly standing room only, no electric outlets, and tiny little tables with narrow (i.e., not enough for a laptop) spaces. They are built to rush you in and out of the car - which seems like a mistake to me, given the way the old cafe cars have been used on the MetroLiners. Makes me wonder whether the people who designed the new Cafe cars ever actually rode Amtrak in the NE corridor, and watched the business travelers rush the old Cafe cars...
