> Trains are pretty awesome, especially in small Europe. Trains aren't really about the region's size. They are about the region's population density and the volume of travel demand between somewhat close urban centers (max 600/800km). > Flying always comes with security hassle. Nowadays trains also come with security hassles. For example, Spain's RENFE enforces security checks, complete with baggage scanning and metal detectors, to board high-speed lines. The key difference is where train stations are located vs where airports are located. Due to historical reasons, nowadays most european cities have train stations essentially in their city centers, whereas airports tend to be >50km out of the city. This means that the door-to-door travel time for any flight must include a >50km trip to the outskirts of a city for then to way out the mandatory 60 to 90 minute boarding process.
