Yes, Amtrak should seriously consider buying Viaggio coaches and cafe cars and of course cab cars. Just a FYI, while MUs would work great on the Amtrak trains that make every single stop on the NEC schedule, bear in mind that if Amtrak were to order both locomotive hauled and multiple unit trainsets for use up and down the NEC, chances are that the equipment assignments will be rotated. There could be times when a MU would cover a faster Northeast Regional while a locomotive hauled train would cover a local. In my opinion, for Northeast Regional trains as well as the long distance daytime trains that use the NEC, locomotive hauled sets would be the way to go. The Amtrak Sprinters pretty much just started running, all of them nonetheless.
