As a Berliner, I probably have taken 100s of pictures of them or, in front of them, shared many moments on those stations. They are a core aspect of the city for me, representing change and, at the same time, the past.
It is based on someone's enormous body of CC-licensed photos of cities in Europe, especially their public transportation systems. [1] – I re-use the photos by assigning them to the station IDs in Berlin's official transit dataset. [2]

I've long wanted to do some kind of google-streetmaps style photography project, taking pictures of all the types to be found in the nooks and cranny of the city, some of which go back centuries. I'd imagine having such a collection of Vienna City Types would be quite interesting to throw at some AI and produce real working fonts.
For typography nerds, cities such as Vienna and Berlin offer so much inspiration, although I would wager the distribution and density is better in Vienna, than Berlin - due simply to the fact that Berlin has a lot more space than Vienna does.

I hope there will be no drive to replace existing signs for new ones (unlikely, given the state of Berlin's finances) - the various fonts used on signage throughout the city makes up part of the quirkiness which makes Berlin so lovable.
Speaking of museums, one of the most charming museums I've ever been to in Berlin is the Ramonesmuseum by Schlesisches Tor. Helps being a fan, though.
