Here are some of the world’s most impressive subways．

The Tokyo Metro and Toei Lines	Features: The Tokyo Metro and Toei lines that compose Tokyo’s massive 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 shove passengers into crowded subway cars so the doors can close. And you think your commute is hell．
The Moscow Metro	Features: 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, marble moldings and elaborate murals. With more than 7 million riders a day, keeping all that marble clean has got to be a burden.
The Hong Kong Metro	Features: 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 Metro	Features: 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 Metro	Features: 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 in1863 and they’ve been running ever since. Some 3 million people ride each day, every one of them remembering to “Mind the gap”.
