Some updates on the public transport situation tomorrow (Friday):
== Long distance trains ==
* Until 10am, trains stop at Berlin Hauptbahnhof * From 10am until the operation is finished (no expected time) all train traffic at Haupbbahnhof is halted

== Public Transport (S-Bahn) ==
* S3/S5/S7/S9 in east->west direction are operating services until Friedrichstr (which is by coincidence the very station you need to use to get to the Friday Venue, CCC Berlin e.V.)
