The main problem is the maintenance facilities not the platforms. The facilities are built for the current Acela length and expanding the buildings is problematic at their locations.Yes. You've got it! That's the whole point of this new equipment order.Amtrak's new Acela Train-sets are supposed to have a 40% increase in seating capacity (or possibly more)--and a 30 year lifespan--which means they could potentially be in revenue service until 2050!A major factor pushing Amtrak to replace the Acelas at 20 years is the limited 303 seat capacity and the 20 trainsets. The Acelas were brought with too few coach cars. . . . Amtrak is leaving a LOT of revenue on the table because of the limited seat capacity and only 20 trainsets.Indeed, if the trains are to be available in the 4-5 year timeframe . . .
28 new trainsets with circa 425 seats will double the Acela class seat capacity on the NEC.

By Amtrak going into distributed power--instead of concentrated power--these new Acela train-sets will have 40% more seats in the same train length.
However, saying something like,
"I wonder why Amtrak did not look into a much longer train-set--perhaps ... this option should have been considered,"
is NOT getting it. LOL. You can be sure that Amtrak considered it. Even if they didn't tell you and me.
As I'm sure you understand upon a moment's reflection, every Amtrak station is obsolete and overcrowded now, and things are getting worse. One of the problems, discussed on this blog from time to time, is that many of the platforms are too short to serve very long trains. Of course, both Penn Station and Union Station are at the small beginnings of massive rebuilds. But the platform issues won't be much better by 2020 or so when we hope to see Acela capacity double.
Now venturing beyond my comfort zone, I'll offer that perhaps the new Acela II trainsets using distributed power could be lengthened in the future, when or if abundant long platforms to serve them become available. But doubling capacity with equipment that is, we hope, newer, better, lighter, faster, cheaper to operate and to maintain, makes this such a very good deal that it's a very good deal within a 20-year time frame. So never mind sweating 2050 and any later years.
