St. Wendelberg in den Alpen
There is a secret area in the inner part of St. Wendelberg, which can only be discovered through a small opening at the front side mountain. From the outside you can see trains disappearing in the depth and re-emerging just below the peak.
Having a look at the inner parts of the mountain, you can see the largest track helix of the Wunderland. It offers more than 170 metres of track, splitting into 12 circles each with a diameter of 1.6 metre, which screw up like a thread. By means of this helix, trains can overcome a height of 1.4 m on a length of 75 metres (this equals a running-time of 5 minutes). Threaded bolts and screw nuts of 16 mm make it possible to exactly adjust the increase of every level.
