> From Riksgränsen on the national border to the Port of Narvik, the trains use only a fifth of the power they regenerate. The regenerated energy is sufficient to power the empty trains back up to the national border.

The twist: these trains aren't connected to the grid. They use regenerative braking to charge batteries when carting ore to the coast, and the batteries power the trip back to the mine.
