The Berliner S-Bahn-Museum documents the history of the S-Bahn Berlin, with a particular focus on technical developments and rolling stock.
Founded in 1989, the institution was long under the umbrella of the Deutschen Bahnkunden-Verbandes e. V.; since 2023 its sponsorship has been with the non-profit Berliner S-Bahn-Museum gGmbH. Out of a small exhibition in the passenger centre at Beusselstraße station a collection developed, which in 1997 moved into a larger substation building at Griebnitzsee station in Potsdam and was shown there until the end of 2016. In the years that followed the museum sought a permanent location in Berlin, staged interim presentations from time to time, most recently 2023–2025 in a project space at Berlin Ostbahnhof. The museum was officially closed on 2 June 2025; many larger exhibits were transferred to a depot. By prior arrangement, individual objects and a small exhibition with a film screening remain accessible in underground rooms at Gesundbrunnen station.
The core of the collection consisted of holdings from the 1980s, when the Berliner Verkehrsbetriebe took over S-Bahn operations in West Berlin. In the 1990s further vehicles, signal-box technology and fittings were added, saved from scrapping by members of passenger associations; this was supported by the administration of the former Reichsbahn assets and the Berliner Verkehrsbetriebe.
After the closure in Potsdam, plans for a new start in Berlin were pursued. An exhibition space planned for Lichtenberg station, with an extensive exhibition concept and several thematic areas, could not be realised because of delays, funding requirements and subsequent infrastructure measures; preparatory work remained incomplete through the end of 2023, funding measures were initiated, and activities there were subsequently suspended.
The future exhibition is intended to be divided into three parts: mobility for the metropolis, technical innovations and the role of the S-Bahn as a political instrument. This focus is meant to make clear the significance of the S-Bahn for transport, technology and society.
