subways
The Tokyo Metro and Toei Lines
Features: The Tokyo Metro and Toei lines that make up of Tokyo's huge subway system carry almost 8 million people each day, making it the busiest system in the world. The system is famous for its oshiya- literally, "pusher"- who push passengers into crowded subway cars so the doorscan close. And you think your ride is hell.
The Moscow MetroFeatures: The Moscow Metro has some of the most beautiful stations in the world. The best of
 them were built during the Stalinist era and feature chandeliers(枝行吊灯),marble moldings and elaborate murals(精美壁画). With more than 7 million riders a day , keeping all that marble
 clean has got to be a burden.
The Hong Kong MTRFeatures: The Hong Kong MTR has the distinction of being one of the few subway systems in
the world that actually turns a profit. It's privately owned and uses real estate development
along its tracks to increase income and ridership. It also introduced "Octopus cards" that allow people to not only pay their fares electronically, but buy stuff at convenience stores ,supermarkets, restaurants and even parking meters. It's estimated that 95% of all adults in Hong Kong
own an Octopus card.
Shanghai MetroFeatures: Shanghai is the third city in China to build a metro system, and it has become the
country's largest in the 12 years since it opened. Shanghai Metro has 142 miles of track and
plans to add another 180 miles within five years. By that point, it would be three times larger
than Chicago "L". The system carries about 2.18 million people a day.
The London MetroFeatures: Londoners call their subway the Underground, even though 55 percent of it lies
above ground. No matter when you've got the oldest mass-transit system in the world, you
can call it anything you like. Trains started in 1863 and they've been running ever since.
