This is Südkreuz Station.
You can transfer to S2, S41 and S42.

This is the S46 line toward Königs Wusterhausen. The Next Station is Tempelhof heading toward Königs Wusterhausen Station.
This is the S46 line toward Westend. The Next Station is Schöneberg heading toward Westend Station.

If you take the south exit from the train station, you can walk down and under the Autobahn to a well known home furnishings retailer.

Südkreuz looks like a giant station and it should. The primary S-Bahn Lines lines are the S2 and S25 (which here we have merged), along with primarily the Ring lines. However, you can avoid the Hauptbahnhof and catch trains heading toward Hamburg, Leipzig or even EuroCity trains to the Czech Republic, Hungary, or Slovakia via Dresden Hauptbahnhof.

Random Experience

This was the first place I discovered that while many of the lines say no drinking on them, the convenience stores here will take your bottle or can from soda (yeah, right) or beer and apply the deposit (Pfand) toward your purchase of something you need (yeah, right. Try toward your next beer.)

I rarely used this station, except when I wanted to visit a place where I could get something or many things that I normally couldn't. So head south, and find out what place that was.
