A plane makes the trip in far less time and does not require the infrastructure investment.
Sure you can drink while you ride but you can also get rolled by the gangbangers who will own this line in no time.
One of the beauties of automotive travel is that you don’t get stuck sitting next to someone who smells badly, passes gas frequently, talks endlessly, or sing rap music for the whole trip. John Rocker was right.
Well, yeah to all that, but I once “got lucky” on a train.
