“More seats: 27% more seats per departure” I think trains are cool. I hope this train doesn’t feel like a budget airline that has no leg room.

Seems like the train set is around 30 feet longer and has more (maybe shorter) cars than the Acela express.

It'd be nice to see the distribution to know if there are some other efficiencies with relation to total length (shorter power cars) or internally (better seat distribution, maybe less first class...). Haven't looked much around, so maybe it's easy to get that info.

I think this is because of adding an additional car in each trainset, rather than squishing seats together.

Acela Express has 8 cars, while the new Avelia Liberty is 9.

Acela is the premium route, so they will likley have pretty good leg room.
