This supplement is also charged for night buses.
This is no longer true.
Night buses now cost the same as any other vehicle.
Also, if you have a one day travelcard this will get you around for one
day, and it will still be valid on all night buses the following night.

Currently plans are made to run the inner parts of the rail network all
night at weekend nights, bringing Hamburg to the same level as "major"
cities like Berlin, Heidelberg and Hannover.
