1.2 miles (2km) of electric rail has been installed between an airport cargo terminal and a logistics depot near Stockholm. The road works by hooking up cars to the ground rail via a moveable arm, much in the same way that trams are connected to overhead power cables.

Electricity is transferred from the charged part of the road to the car’s battery, helping to solve the issue of keeping electric vehicles topped up with enough energy. The arm can easily be disconnected to help cars overtake as well.
