Magnetic levitation will be one of the cornerstones of global transportation in the near future: just take a look at concepts like these to easily realize this.
It is a system that eliminates friction between the parts, reaches speed unthinkable for current systems and can shorten distances decisively, allowing a new, healthy decentralization of work and social activities and favoring demographic redistribution and decongestation of megacities. All at more than 500 kilometers per hour :)
In the drawings of Vanja Valencak the new Maglev is equipped with photovoltaic roofs: they will allow the system to optimize energy management and (once the costs have been ironed out, which today they are huge) will contain prices for passengers. Not us, perhaps not our children, but our grandchildren they could wake up in Rome at 7:00 am morning and find each other at the office in Milan by 8:30.
It will be another life.
