And 166 of them are ugly as sin. That’s Berlin’s subway system for you, folks.
But, hey. Beauty is in the eye of the Schwarzfahrer (“black rider” or fare dodger). So enjoy them already or something.
The city’s U-Bahn system also felt the impact of the Berlin Wall, which divided the city for nearly three decades. Many train lines pre-dated the Wall, so some of the West Berlin lines necessarily passed through East Berlin stations. These stations were closed and guarded, and became known as ghost stations. The guards were visible to the West Berlin passengers as the trains slowly moved through the dimly lit stations.

I remember many a ride on the Berlin U- bahn. I was for bidden, by the US Army, from going on any line that passed through East Germany because of my security clearance. So I can’t claim I ever went through one of the ghost stations.
As long as the trains work, I don’t care what the stations look like 🙂
