The trains have chair tracks, like airplanes. The interior is reconfigurable. The tracks even run through the bistro, so that could be removed if desired. Some of the bicycle storage areas also have flip-up seats that can be used if there aren't too many bicycles, but unlike all the other seats not all have electric outlets. All in all, rather nicely designed and with good fit and finish.

As is obvious, this is a new service. I would be greatly surprised if they get everything right on opening day, but they don't have to as long as they (the cars and the people) are adaptable.
