Build a skilift going across the mountains.
Make sure that it is a continues circuit.
You may also dig out a small amount of ground if necessary.
There must be more then one car.
The car and the station must fit in the green boxes.
The cars must pass through all the green boxes.(stations)
You may use scripting.
The car must also slow down and detach from the cable in all of the stations.
Good Luck.
