Where are all the coach cars for these seriously extended eastern LD trains being proposed here supposed to come from? Amtrak has only 120 LD coach and 25 cafe/lounge Amfleet II cars available. Amtrak needs to order Viewliner LD coach and cafe/lounge cars, but that is likely years away (unfortunately).
For me, this was in an ideal world. Something like this could be reasonable, since it does not go over the total options limit. The coaches would have to be Viewliner 2 coaches, but I doubt that. I've heard people talking on here talking about Florida corridors as good uses for the Horizon cars once Illinois gets its bi-levels, since the demand will soon be there and it never gets too cold. So for any of the tack-on cars, I was thinking that it would be reasonable to use Horizons, so that no new equipment would have to be ordered.
