I don't dispute the demand.
A loco operating it will have some success for those wanting to visit the Greater NYC area but without through ticketing and access to further afield it will never achieve its potential.
The idea of a loco without that will still mean that most of the business pax to the USA would likely go with the recognised carriers.
I have no doubt it could work but I am sure they would rather see Continetal or Delta pick it up than a loco, as once someone is on the route it seems unlikely anyone will compete.
We don't seem to have heard much noise about the chances of it which I suppose could mean anything.
Ofcourse, I'd rather see a loco than No- Co but it could limit its potential.
