Maybe Amtrak is considering this for the new rolling stock of eledtric locomotives and Viewliner II's. It would be a great way to grab someone's intention, proclaiming "yes, our railroad is still around, and we're buying new trains". The present incarnation has been around 16 years, since the introducction of the original Viewliners, which is longer than any other in Amtrak's history. Phase II was from 1976ish to 1982, 1983 to 1995 was phase III. This Phase IV has long outlivd its welcome. Drat the IV, and good riddance.
