Copenhagen Podride is a series of podcasts created for passengers on the Copenhagen subway, the S-Trains. The podcasts contain stories about the urban and sociological development along the S-train lines. Stories are divided into chapters that match the S-stations, thus making it possible for passengers to get a location-specific story as they ride by. The service is free of charge and available for download on the web, or on your mobile phone via SMS.
Sweet idea for any city trying to attract more people to its public transportation system. Denver, you out there?
