If you dont't like flying or want to avoid airport congestion, delays restrictions and cancellations, there isn't an alternative for long distance travelling.
Magnetic Levitation Trains(Maglev Trains) use electromagnetic propulsion and suspension to reach speeds over 310 mph(500 km/h). At the speed, trip from Rome to Paris on a Maglev would take 2 hours but engineers believe the trains will get faster. Maglev train systems are being built or are planned for construction on most continents. Currently, the Maglev train in the world is in Shanghai, china. How it works. Magnets underneath the track Levitate and float the train
Along the sides of the track is a guideway with magnetic coils that alternate polarity to interact with magnets on the tarin.
projects are trying to improve these trains by using a higher temperature superconductor, as superconductors lose conductivity above their critical temperature. Historically they have needed to be cooled with liquid helium(4.2k) to work, but Schultz is working on YBa2Cu3Ox materials that only need to be cooled with liquid nitrogen(77K).
The main impediment to speed is air resistance, which is why engineers are excited about Maglev trains through Vacuum tunnel-tubes. if this was to occur then Maglevs could potentially reach super-sonic speeds
