A while ago I made this: https://derhuerst.github.io/berlin-subway-guide/

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]

While we're doing historic metro buildings, I also love the old Art Nuveau Otto Wagner stations in Vienna: https://coeser.de/blog/index.php/2020/08/18/wiener-highlight... (Text in German, but lots of images)

I'm really surprised by the variety. Having lived in Berlin for 6 months I completely missed that detail.
