Wikipedia was used to provide data such as daily ridership, length, opening year, and interesting facts. Please note that ridership can vary depending on the year and the years used for ridership are not consistent for this video. Unless noted otherwise, ridership is weekday. -Data is up to date as of 2018 - there are expansions happening across many systems in Europe, some footage used in the video may be old because it was difficult to find footage for certain systems or I was using my own footage from years ago. Changes are happening to a lot of metro systems and the video does it best to showcase as much up to date information as possible. Metro maps also proved to be a challenge to collect as some systems include heavy rail lines while others don't. - Unless noted: ridership refers to daily weekday ridership For complete videos of the system: Amsterdam:    • The Metro System of Amsterdam, Netherlands...   Athens:    • The Metro in Athens, Greece - Μετρό στην Α...   Barcelona:    • Metro in Barcelona, Spain  2009   Berlin:    • U-Bahn/Metro in Berlin, Germany 2017   Brescia:    • U-Bahn Metro Brescia   Brussels:    • The Metro System in Brussels, Belgium   Bucharest:    • Subway / metro / metrou / underground Buch...   Budapest:    • Super Modern Metro in Budapest, Hungary   Catania:    • Видео   Copenhagen:    • Subway of Copenhagen, Denmark 2014 - Køben...   Dnipropetrovsk:    • Поезд метро на станции Заводская - Днепроп...   Genoa:    • Metro Genova Partenza da / Leaving from Sa...   Glasgow:    • This is the Tiniest Subway in the World! G...   Hamburg:    • U-bahn in Hamburg, Germany - the Metro of ...   Helsinki:    • The Subway/Metro of Helsinki, Finland - He...   Istanbul:    • Istanbul Metro M5 Line | Driverless Metro   Kazan:    • Казанский метрополитен | Kazan Metro [2016]   Kharkiv:    • Харківське метро. Салтівська лінія   Kiev:    • Метро в Киеве: The Metro in Kiev, Ukraine ...   Lille:    • The Metro System in Lille, France - 2016   Lisbon:    • The Metro/Subway in Lisbon, Portugal   London:    • The London Tube - Metro - 2015   Lyon:    • Видео   Madrid:    • Madrid Metro - Line 8 - Aeropuerto T1-T2-T3   Marseille:    • The Metro de Marseille, France (Rubber-tir...   Metro Bilbao:    • Spanish Trains  - The Bilbao Metro   Milan:    • Metro a Milano: The Metro System of Milan,...   Minsk:    • Minsk Metro Ride   Moscow:    • Метро в Москве: The Beautiful Metro System...   Munich:    • U-bahn (subway) in Munich, Germany   Naples:    • Metro Napoli LINEA 1 " Piscinola - Secondi...   Nizhny Novgorod:    • Метро в Нижнем Новгороде - The Metro in Ni...   Nuremberg:    • U-Bahn Nürnberg 2016 - The Metro in Nuremb...   Oslo:    • Oslo T-bane - The Metro in Oslo, Norway 2017   Paris:    • Le Métro à Paris, France 2016 - The Metro ...   Prague:    • The Prague Metro/Subway 2011 - Metro v praze   Rennes:    • [Rennes] VAL 208 Métro - Départ J.F. Kenne...   Rome:    • So Much Graffiti on the Metro in Rome, Ita...   Rotterdam:    • Metro systeem van Rotterdam, Netherlands 2017   Saint Petersburg:    • Exclusive: St Petersburg's Metro System (М...   Samara:    • Самарский метрополитен   Sofia:    • Транспорт в София, България - Local transp...   Stockholm:    • The Metro System of Stockholm, Sweden - St...   Toulouse:    • Métro Toulouse VAL 208 SANS CONDUCTEUR   Turin:    • Metropolitana di Torino   Newcastle:    • Metro in Newcastle, UK - Tyne and Wear Met...   Vienna:    • The U-bahn/Metro of Vienna, Austria, 2016   Warsaw:    • Poland, Warsaw, metro ride from Wierzbno t...   - Thank you for your support.
