Europe has quite a few high-quality, high-speed rail connections. If I may suggest a feature, in order for the tool is to be faithful to its mission, alternative mods of transport could be supported as well.
Personally, I am more than happy to take an overnight train than a short-flight, given the additional overhead of travelling to/from the airport. An overnight train can take you pretty far within continental Europe.
