Have you ever thought about subways? They have many names, including the Metro (Washington DC) and the Tube (London). The London Underground is the oldest, opening in 1863. The Paris Metro is very convenient. Every building in the city center is within 500 meters of a station! More people use the subways in Moscow than in any other part of the world, and it is the fastest in the world. Some of the trains go as fast as 120 kilometers per hour. And, of course, Tokyo is famous, too – for the pictures of people pushing other people into the cars so that as many people as possible can fit.（by Prof. Carmella Lieske）
