The city of the future will be cleaner and greener because of solar and hydrogen energy. Elevated hydrogen trains (Hyrail) will be powered by solar energy that electrolyzes water for fuel cells. This electricity will power MagLev Hyrail trains.
Also running through future cities will be, at ground level, hydrogen fuel cell trains (or Hydrail). While Hyrail will most typically be passenger trains, hauling people around the future cities, Hydrail will be using the power of hydrogen fuel cells to haul cargo inside and outside of town.
