The project is still under construction, the cable car's are not going very smooth on the pole's. If someone has an idea to solve this problem, let me now. If you have other comment's ore problems let me also now, i will try to help where i can.

Extra material.:
You need 12 bearings from the type 623zz. These are used in the pole's and pully's.
As a motor i used the small dc motor from amazon. You can feed this with 2 small AAA batteries in a holder. The cable for the motor you can feed thru a spare box in the under station. If you not glue the roof on you can power on by just stick i
