I´ve visited Paris in August 2011. So, I made some videos from Paris stations. This one is from station PONT CARDINET with really strong traffic. Video is about 7 min. long and I´ve captured it during 10 minutes.
Actually it is not so surprising that there is strong traffic here, as Pont Cardinet is very close to the Gare de St. Lazare, one of the busiest railway terminals in Paris, which handles mostly suburban and commuter trains.
