(1) I think there'd be a good market for good food to buy in Smart and Premium. Think "ekiben" on the Shinkansen. Please, anything other than chips and crackers!
(2) Is this cell based or sat based?
(3) This is interesting to be the highest rated (except staff) component. Ideally, me personally would try to arrive just minutes before departure. I say that, but I lie. I have waited for 30 minutes in the select lounge. But that's what sets train travel apart from air. Efficient arrival to the station before having to board.
(4) I can't wait to experience this!
I know everyone is calling this "higher speed" rail, and not true HSR. For comparison, when the Shinkansen opened in 1964, it's top speed was 135 MPH, so only 10 MPH higher than Brightline's top speed. Of course, that was 60 years ago and provisions were already in place to eventually allow up to 185 MPH today...
