Stellwerk Fichtengrund is a decommissioned railway signal box on the outskirts of Berlin in Oranienburg, Germany, formerly in the GDR.
The Stellwerk[2] operated a type GS II DR[3] point control system and the structure was designed by the building department of the Deutsche Reichsbahn.
[4] The building consists of a block containing the control centre with radial viewing windows and a separate part containing the electrical relay rooms.
The construction of all walls, floors and roofs is predominantly from pre-cast or in-situ cast steel reinforced concrete with a rendered outer coating on the walls; building materials and method which were fashionable during that period in the GDR.
The Reichsbahn built several virtually identical buildings situated in Birkenwerder,[5] Satzkorn,[6] Hohen-Neuendorf-West[7] and Schönfließ.
