Thanks to the Berliner Unterwelten e.V., there is the opportunity to show small selected exhibitions in a converted former underground toilet facility near Gesundbrunnen S- and U-Bahn-station. Films on S-Bahn-history are shown, too.

The exhibition is open to the public every last Saturday of the month be-tween 1100 am and 5 pm. The regular fare is 3 €, children (7-14) pay 1 € 

The museum is also present at „open door events“ or other public activities. The collecting continues until the new Museum will be opened.
