Description:
At Coimbra B train station, sets of bells ring to warn of approaching trains, so that pedestrians move away from the track crossing. The bells are arranged so they swap tones, creating a fascinating and distinctive Doppler effect - you can also hear announcements and a passing police siren in this rich field recording.
