CONSERVING ON BRAKING AND ACCELERATION.

Tyler "Marginal Revolution" Cowen discovers how skipping stops works.  "Acela Nonstop will get you to your destination only about 15 minutes sooner than the regular Acela service."

Why should the Acela Nonstop be any different from the nonstop Metroliner experiment of forty years ago, which attempted to make Washington, mostly without success, from New York in 150 minutes?  The ordinary service had trouble making the run, inclusive of stops at Newark, Philadelphia, Wilmington, and Baltimore (and the Metropark and Capital Beltway stations) in three hours.

That non-stopper?  Two hours and 29 minutes, in other words a governor error faster than the old Metroliner.  (That service didn't last, as it passed up a lot of the Baltimore to Philadelphia or Philadelphia to New York or Wilmington to anywhere business.  I wonder if a rising politician called Biden raised objections.)

North of New York, all of Acela's end-to-end time advantage is in skipped stops compared with more ordinary trains.

But nobody wants to put any money into more direct trackage.  News flash: widening the turnpikes isn't going to help either.
