I think the car windows should have been made bigger to provide a better view from the aisle seats. Would structural considerations have precluded that?

Would structural considerations have precluded that?I think it's interesting that these cars, that have no seating in the cafe, have low windows and the Acela 1, which at least has some seating in the cafe, has high windows. Go figure.

I do not understand the math of catenary. The power companies have to deal with it ongoing from local lines to major high voltage lines. It is apparent that PG&E did not understand it enough and had many fires caused by the lines contacting burnable fuel in California.Yes, a wire harness in the Acela II sends power the length of the train to the trailing locomotive. If the front pantograph fails, it can raise the trailing one and use that. The trucks are also interesting; it's a more unified trainset than the old Acela (see the video below).
Back to Amtrak. It is well known that the PRR style CAT has problem if an EMU train has too many PANs that bounce can cause problems.. All the Acela-2 passes have just one pan up. I am still uncertain if one pan can supply both locos or if the one loco is able to push or pull the whole train ?.
As for the catenary, this Amtrak manger goes into great detail at 1:08:
The video was posted on these forums recently by Mass Bay RRE. There are two types of cat on the NEC. And the Amtrak manager doesn't see that changing.

The 50 only applies to running a set with the front shroud raised, being towed by another engine is 125 max

Trainset 1 returning to Hornell.
Also, the 50 mph restriction on the new trainsets only applies when 1 of the shrouds is open and not actually coupled to anything. If the trainset is bracketed, they can do track speed (79-90 mph).
