Love taking the U1 to work and getting overground after Kurfürstenstraße. It is even better when the sun is shining and I can close my eyes and enjoy a few seconds of warmth.

Legend says the U1, which was the first tube line in Berlin, was built overground in Friedrichshain and Kreuzberg, because people living there wouldn’t be bothered with the noise and dirt. But Charlottenburgers didn’t want that noise and dirt in front of their windows so the tube had to be built underground.
