Finally I present you the detachable 3Sropeway with an intermediate station. Besides more than 20'000 lego parts there are around 400 gears, 2'000 chainlinks, and 36 motors.
13 gondolas run at a distance of 25 seconds between the stations, inbetween I placed 4 masts. The intermediatestation is around 2 meters long.

In total there are 36 motors to operate the ropeway. 8 of them are used for the haulrope and 16 to power the conveyorsystem.
The stations at the end are equipped with pneumatic cylinders that automatically correct the tension of the haulrope. It's aircompressor is controlled via RCXbricks (the very first MindstormsSystem). Lightsensors detect the distance inbetween the gondolas and correct it if necessary by partially slowing down the conveyorsystem.

A further gimmick are the blue rotationsensors in the stations. They detect if the rope fell out of a deflection pulley by supervising the differential gearboxes located in the center of the stations. If the differential gearbox starts turning, the rope fell off a pulley.

If you have any questions ore advice, please comment or write me a message.
