I for one hope this is not a one-and-done order, and that it will lead to a sustained long-term program of Superliner long distance equipment replacement as well as additional corridor equipment. (unfortunately "long-term" seems to be a dirty word in Amtrak land due to the whims of politicians). Looking at the
specification, they have notional designs for a coach, cab/baggage/coach, and cafe. It should be pretty simply to make any necessary mods to allow the same carbody to be used for long distance cars (converting to single doors on each side, having only one staircase between levels). Even if it was only a few cars a month, if it could be sustained for years it would go a long way towards updating the fleet. (I hope the same happens with the Viewliner II line, continue to churn out additional cars (including Viewliner coaches) for years to begin replacement of the single level fleet.)
