Trainstations in the south of Berlin

Two drawings of my favourite trainstations in Berlin:

The first one is the U-train station Dahlem Dorf, which is sited directly next to the open air-museum and ecological farm Domäne Dahlem, where old breeds of farm animals are kept and bred.

The other one is the S-train station Mexikoplatz. One of the few Art Noveau buildings in Berlin.
