The Bullet Train, also known as the "Shinkansen", is named due to the train’s speed and shape. It is a network of high-speed railway lines orginally designed in Japan.
Starting with the 210 km/h (130 mph) Tōkaidō Shinkansen in 1964, the network expanded to link most of the major cities in Japan at modern speeds of up to 300 km/h (186 mph).
The network stretches across the United States, connecting cities like Phoenix, Gotham City, Hub City, Jefferson City, Kansas City and Smallville.
In the real world, in Japan, the line is the world's busiest high-speed rail line. Carrying 151 million passengers a year it has transported more passengers than any other high speed line in the world. Between Tokyo and Osaka alone ten Tōkaidō trains (16 cars each (1,300 seat capacity)) run per hour with a minimum of 3 minutes between trains.
