> Plus train trips just take longer, leading to higher crew costs. I assume you're only talking about time onboard, not door-to-door time (where high-speed rail generally beats short-haul flights), so I won't dispute the time aspect. But in order to calculate crew costs, you'd have to know crew density, and my impression is that crew/passengers is several times higher for planes than trains.
