Which by and large are exactly what the state sponsored/short haul trains are geared for. Yes, there are a few exceptions like the Adirondack and the Vermonter (even though those trains do still manage to carry some business travelers), but most State sponsored trains are all about the business traveler.
And NEC trains are... not?
They are, but no further expansion of those trains is needed at present.
While I admit that the NEC is unique, having that ultra-high population density-- I am sure the contention could be made that if the other corridors were as developed as the NEC the "state sponsored" revenue would be through the roof.
At a loss, yes, but you could easily eke more money out of those areas.
No doubt.
But then the same can be said for the LD's too. Increasing train length would generate more revenue, as would have two trains per major route. And while I don't subscribe to all the theories espoused by URPA, it is clear from Amtrak's numbers that increasing revenue on at least a few of the existing LD's like the EB probably would result in those trains actually making an above the rails profit like the Auto Train does.
Business/commuter runs have little hope of that. Acela only earns an above the rails profit because Amtrak considers maintaining the NEC to high speed standards to be a capital expense and not an operational expense. Not saying that's wrong, as I do believe that it really should be a capital expense. But listing it thusly does hide the fact that the NEC isn't profitable like many believe.
