Stellwerk Ahlhorn, Signal box in Großenkneten, Germany.
Stellwerk Ahlhorn is a railway facility in Groszenkneten that combined two purposes in one structure: a signal control room on top and an integrated water tower below to supply locomotives. The brick building still shows its original design and is now protected as a cultural monument.
The building was constructed during the era when railways were expanding into this region and served as a key control point for train operations. After decades of neglect and facing demolition by Deutsche Bahn, restoration work around 2020 saved and rebuilt the structure.
The signal box reflects how railway workers organized their operations and the structures they needed for this work long ago. Today it serves as a place where visitors can appreciate and understand this industrial heritage.
The building is now operated by a foundation and welcomes visitors interested in learning about railway infrastructure history. Planning a visit during regular hours and checking ahead about access and guided tours will help you make the most of your time there.
A model manufacturer named Faller created a detailed miniature replica of this signal box at 1:87 scale, bringing attention to its distinctive architecture. This recognition demonstrates how noteworthy the building's design truly is.
