Balder is a wooden roller coaster at the Liseberg amusement park in Gothenburg, Sweden.

This means that the track is manufactured to a higher degree of precision than could ever be achieved by hand.

The track also is made of more layers of wood that are tightly bonded together instead of nailed together by hand like a traditional wooden roller coaster.

The riders benefit from a coaster, that while being wooden, is near steel smooth.

Three other prefabricated wooden roller coasters currently exist, Colossos at Heide Park, El Toro at Six Flags Great Adventure, and T Express in Everland.
