The main rails of the trolley consist of steel pipes — an up track and a down track. A special maintenance trail is reserved between the tracks.

Building this trolley was no easy feat. It required more than 1,000 metric tons of steel, which is hard to carry when there's no road for large machinery or equipment. Materials were carried by hand to the construction entrance along the cliff path. Workers installed four ropes with pulleys to slide the materials to the site.

When people enter the trolley car and look down to the valley floor, they can take in a variety of views depending on the vertical angle of change. For the observant, there's not only picturesque and precipitous scenery but also beams of sunlight on a waterfall, which form a perennial rainbow.
