Maglev Trains are trains that flout on a magnetic field. Eliminating friction by having no wheels maglev trains can travel much faster then old school trains. Germany and Japan are the two countries that are pioneering this technology as far as I’m aware.
Building pipelines through out our provence is insane, backwards and counter productive, but building maglev bullet trains to connect major cities is something I could get behind and advocate.
Maglev trains are fast but if your interested in something even quicker check out the HyperLoop
