Bratkinson, half of what we say on this board is just barely within the laws of physics, let alone what current Amtrak management wants to do.
Anyway, I'm not sure Anderson has shown he wants to get rid of sleepers
1 and 3: He' wants more short-haul corridor service that can compete with planes and cars; he seems to think that short consists that can run cheaply enough to offer several trips a day are better than longer consists. He doesn't want one-a-day LD trains with expensive non-revenue cars (diners, lounges, probably even baggage cars), cranky host railroads, awful OTP, and a lot of "experiential" passengers. He doesn't think they are serious transportation. But he might go for reassigning sleepers to an NEC night train where Amtrak dispatches the whole route and can ensure excellent OTP especially for a night train with few other trains to interfere, a train that could compete with really early planes or evening flight + hotel, a train parallel to a really awful set of options for driving, with endpoint cities where you're better off with no car, and a dozen complementary day trains.
2: Anderson wants to save money with contemporary dining:? Try saving even more with no dining at all. The target passengers have never been in a sleeper and have no idea that a sleeper could come with free sit-down meals, because their only train experience is Acela or maybe a regional, MARC, or the T, or maybe a long-ago Night Owl, which didn't carry diners; plus, the train leaves after dinner and arrives before breakfast.
4 and 5: Amtrak has never had enough money for maintenance. Anderson may not be interested in maintaining 40 year old cars to make good LD experiences. That doesn't necessarily mean he isn't interested in maintaining 20 year old Viewliners if he can use them to run a competitive short-haul sleeper.
In fact, if my utterly sensible and totally unlikely idea ever happens, I have a name for it: The Anderson Sleeper.
