Unterburg trolleybus turntable

The Unterburg trolleybus turntable is a mechanical rotating platform in Solingen that turned vehicles around using a circular base. The system worked with rails built into the ground to help trolleybuses maneuver in tight spaces.

The facility was built in 1959 to replace earlier tram services with trolleybus operations. It served line 683 until its closure in 2009, adapting to changes in regional transit.

This site reflects how Solingen solved transportation challenges in a narrow river valley during the mid-1900s. The turntable was part of a network that moved residents and workers through difficult terrain.

The site sits in a narrow valley and is mostly visible from the outside, as the facility no longer operates. Visitors can view the structure from nearby paths or elevated areas, depending on access to surrounding walkways.

This turntable is one of only four surviving trolleybus-rotating devices left worldwide. Similar structures once existed in Great Britain and Mexico, but most were dismantled, making this a rare remnant of technical transit solutions.
