Yeah, the tram lines were mostly torn out of West Berlin in the 1950s to make more space for cars. They're still all over the east, and there's been some very recent construction including a tram line that goes to the main railway station.

You've still got pretty good buses in those areas, though. Our main public transit problem lately is construction and/or strikes that shut down large parts of the S-Bahn.

The streetcar lines were removed in the west, but all of East-Berlin (about 1/4th of the city) still has them.

It's mostly underground now.
