By closing all the checked baggage options, Amtrak would "save" money on paper, but it would be bonkers, as it would cut the numbers of passengers considering using their trains.
Same with closing Metropolitan lounges... It may bring in revenue from rents, but that won't increase sleeper passenger's bookings, most of whom are mature, and value the amenity. Amtrak are not in the business of being landlords, they are in, or a least should give a passing nod, to the business of attracting and retaining train passengers!
I love the grand old station designs, and would much rather pass slowly, with less convenience, through a 1930's artistic building than whizz through a modern design. When did anyone notice the beauty of an airport?
Earth without art is Eh, as the saying goes...
