Something else just came to mind:
Since your chair is an electric, I imagine, it's powered by some type of battery.
You might want to check with Amtrak re: of travelling w/battery or batteries re: any probs. in your trek.
I know that with scooters and other power chairs, airlines have certain guidelines or travel requirements depending on the type of battery used to power DME.
May as well add this here:

It's a direct link that delineates Amtrak's acceptable wheelchair specs.
When I travelled, Amtrak also provided me with an x-tra seat at no additional cost; it was for when I wanted to collapse my chair; it remained beside me - in front of the x-tra seat.
On part of the trek, I sat in my chair; the "disabled" car was filled to capacity, and an elderly woman and her travel companion would not have had a seat so I gave up mine.
I also made sure to take proof of disablity with me, in case it was sought and for any security stuff; I wasn't taking any chances
