Is that always true? In France HSR stations are often like airports, way out of town and you have to get a taxi in/out of wherever you're going. And the rail network seems more exposed to mechanical breakdown in general. I don't have hard data but it feels to me like trains fail or get cancelled much more often than flights do, and when a flight does get cancelled it's usually due to some major failure that'd take out trains too (e.g. power failure).
