1000 kilometer in a 100km/h average German ICE (average on the trip I took including stops in between) is ten hours. Plane flying 900 can do it in one and a half. Even if it's the ideal center center trip and allowing for two hours of boarding and an hour to and from the airport, flying is nearly twice as fast. Now if it were to be the much faster French Thalys they can average 150 (including stops) on the route I did but it's still an hour difference. I'd say French Thalys is competitive up to 700km for direct center center trips. German style HSR is interesting only as an alternative to a car.
