Ok so here is a picture of a roller coaster Named Viper from Lightwater Valley amusement park. In this picture there is a tower column that appears to have a motor on it and may spin around, but a wide enough top to almost be meant to hold a piece of track. All the pics show this being used for nothing, except one and that was the third park to own it and put a dinosaur on it. This is a Schwarzkopf City Jet model, but if anyone could possible tell me what that main out of place support piece may have one time been for I would be so very thankful, I just cannot to seem to find an answer.. http://rcdb.com/1819.htm?p=10165 and a good pic of the tower http://rcdb.com/782.htm?p=1243

Yep that's exactly what it is.  Take a look at this photo of the same model of coaster.
