In brief: The Korea Advanced Institute of Science and Technology (KAIST) has developed a prototype inductively-charged train called the OLEV (online electric vehicle).

The word

KAIST OLEV

The OLEV demonstrator replaces a trackless combustion engine train which runs inside Seoul Grand Park in Korea. The OLEV uses non-contact magnetic charging through underground cables.

KAIST sees this method of charging electric vehicles while running, parked, or otherwise engaged as necessary for the development of commercialized EVs.

The power cables to run the OLEV are buried under its pathway in the park. Through induction, the train picks up the power while running or parked on the roadway, recharging it's small, on-board batteries. This mitigates the need for large, on-board battery packs and and their related expense.

The power source itself, under the roadway, is activated by sensors which turn power on to each road segment as the vehicle passes. This eliminates what would otherwise be a constant electromagnetic field around the roadway and wasted energy through loss during times the road is not being used. The EMF emissions are well under the 1998 ICNIRP guidelines.

And so ...

Very interesting concept and definitely something of use to vehicles would travel on a fixed or geographically restricted route.
