The City Cycling challenge is a 3-week event that encourages Berliners to leave their cars at home, strap on their helmets, and cycle as much as they can. Participants join a “team,” and whichever team has cycled the most at the end of the challenge becomes the grand champion.
The Berliner Verbindungsbahn (the Berlin Connector Train) was built to connect 5 large train stations around the city. These train stations were built as so-called Kopfbahnhöfe, or Terminus Stations, meaning that trains rode in and out on the same track, and didn’t come in one end and out the other. This meant that it was super difficult to get from one train station to the other. The Berliner Verbindungsbahn was a street-level rail system that connected each of the 5 main stations. It was taken out of service with the completion of the Berliner Ringbahn, which is still in service today.
