Obviously, one of Amtrak's more obnoxious problems has been the fact that they've had to retire cars (due to age, damage, EPA rulings, etc.) and haven't been able to arrange replacements (until recently at least somewhat justified by low, stagnant demand). The fact that there aren't gobs and gobs of reallocated sleepers floating around from various trains and that the Nite Owl had to have its sleeper cut a few years back is testimony to this. With that said, does anyone know what the long-term trend has looked like in terms of sleepers and coaches?
