The funicular actually consists of two parallel lines. Each line has a passing loop and two cars, and operates on the funicular principle by which one car counterbalances the other, but the two lines can operate independently, allowing either two or four cars to be used depending on demand. Each of the cars can carry up to 168 people, a journey takes 63 seconds, and the line has a maximum capacity of 7,200 people per hour. The funicular is approximately 200 metres (660 ft) in length, overcomes a height difference of 38.7 metres (127 ft), and has a constant slope of 19.7%.[3][4]
