My summer vacation this year went to Berlin. I spent a week riding trains, photographing tracks, sketching track maps. Like last year I had no trouble with authorities, despite people in DB Sicherheit uniforms often being around as I took pictures.
Unlike last year, this year I've taken the time to draw fair digital track maps from my photos and sketches. The first part of the results are now available at http://trackmap.net/de/bea. More will follow in the coming weeks. I hope.
