New and unique worldwide! The rack railroad from Vitznau to the Rigi, opened in 1871 as the first mountain railroad in Europe, already had a turntable with two intersecting rack tracks at the bottom station to enable the connection between the 2 station tracks with the 8 tracks of the depot. Switches are not possible for this due to the local situation.Now, Rigi Bahnen has ordered 6 new double-unit railcars, which are longer than the tracks on the turntable/ the diameter of the turntable. In order to be able to drive from the two station tracks into three of the depot tracks without having to turn the turntable, 3 crossing tracks are now needed, two of which runs in a slight curve. Work on this globally unique construction, developed by the engineer Theo Stolz, is underway. One track is straight, the other two are laid in a slight and a stronger curve respectively. And in the middle 3 cogwheel tracks are crossing each other. The 2 station tracks are in the foreground right, the 8 more or less curved depot tracks go to the left. And behind the ship station building is Lake Lucerne and Bürgenstock mountain.
