"Hailed" by many people many times over the last 100 years but the idea has mostly not worked in many countries. From what I can work out, the economics don't scale in the way we would assume. 200 people on a train sounds like a large economy of scale, and indeed, on the excursion trains we have been on, it is cheaper than a normal 1st class ticket for a longer journey even with 20-30 paid employees aboard but I don't think the access charges work for regular trains. Hopefully they can work in the US although from what I understand, the Eastern seaboard is much more setup for passenger traffic than the rest where you are more likely to get slow average speeds or frequent stops for single track. At the same time, people who compare the plane usually compare the air ticket to the train ticket, not the ticket to the airport, the things you might buy there, the time you have to waste waiting, the car parking at both ends etc.
