New York City

Though New Yorkers may complain about the subway, the New York City transit system is in fact one of the best in the world, thanks to its wide reach and the fact that it runs 24 hours a day—barring extreme weather, that is. Part of the Metropolitan Transportation Authority, the largest transportation network in North America, the subway opened in October 1904 and provides easy access to Manhattan, Brooklyn, the Bronx, and Queens. It's so expansive that if all of NYC’s subway tracks were laid out end-to-end, they would stretch from New York City to Chicago. Featuring 21 routes, approximately 1.7 billion people use the subway’s 468 stations each year, making it the most-used system in the U.S. Always making improvements, the MTA opened the new Fulton Center transit hub late last year; the staion features a massive skylight to brighten up the commute.

Known coloquially as the Tube, the London Underground is the oldest underground railway in the world, dating back to 1863. The first electric line debuted in 1905, and today the Tube travels an average of 20.5 miles per hour through 270 stations. With plans in the works to update the system to stay ahead of the curve, Transport for London hopes to add 250 trains to select system lines, create air-cooled carriages, and increase accessibility and reliability to carry trains through the 2060s. A number of notable names have taken historic trips on the Tube: Queen Elizabeth II became the first member of the British royal family to ride the system when she sat on the Victoria Line after it opened in 1969, and Mark Twain was one of the first passengers to ride the Central Line when it opened in 1900.

The Paris Metro is one of the densest subway systems in the world, with just over 132 miles of tracks running through 245 stations within the 40 square miles that make up Paris. Dating back to July 1900, the system is known for its notable Art Nouveau-styled entrances, designed by Hector Guimard, though only a few remain in existence today. The Greater Paris Metro project is in the works to upgrade the entire subway network, which more than 1.5 billion people use each year, by 2040.

The 102 metro lines span 200 miles.

When construction on the Athens Metro began in 1992, builders also took part in the largest archaeological excavation of a modern city, which led to the discovery and preservation of more than 50,000 artifacts from the classical Greek, Byzantine, and Roman periods. Today, these items are on display in metro stations throughout Greece. The Athens Metro system, which has reduced traffic and smog in the area since its establishment, is made up of three rail lines and 65 stations, with more still in the works today. The trains travel up to 60 miles per hour beneath the historic city, meaning you're guarenteed to get to your destination with plenty of time to spare.
