Was fährt is really pushing these days, already releasing their 17th(!!) episode. Amongst others, shot by Kevin Schulzbus, these videos offer current traffic spotting from Berlin, on Metros and S-Trains alike.
In case you want to see some rolling pieces, check the 11th episode of Was fährt. As usual, the edit is relaxed and the selection is rather broad: from full on burners, partly buffed pieces to tags, everything whats currently running on Berlin subways is shown.
