An old park map, 1980s perhaps, shows a figure eight roller coaster called Berg-Dalbana.  This is the only reference to this roller coaster found to date.

Purchased by Parks & Resorts Scandinavia in 2010. Prior to this the amusement area was rented to Axels' Nöjesfält (Axels Tivoli), an operator of transportable rides on contact with parks in Sweden and Norway.
