Copenhagen has an interesting transit system despite the abandonment of the trams in the early 1970s. The "S-tog" (essentially, commuter or regional metro trains, similar to an S-Bahn in Germany) have been running since the 1920s, and the city's rail transit was enhanced by the addition of a fully automated, driverless Metro in 2002. Most of the pictures and all of the films here portray the Metro.
I only have pictures of two Metro stations; in both cases there are also some pictures of the S-tog:
Please note that these films were made with a digital still camera (my Canon Powershot G2), so the quality is so-so.
