Elon Musk's Hyperloop is just a pipe dream, but these superfast trains are already up and running.
World's fastest trains
With Elon Musk's next-generation transportation system, the Hyperloop, recently unveiled, many are calling into question moving forward with high-speed trains.
Musk claims the Hyperloop will cost a fraction of what's need to pay for high-speed rail projects. For example, California's high-speed rail route from San Francisco to Los Angeles is currently budgeted at $68 billion for a trip that will take 3 hours. Musk said the Hyperloop aims to make the trip in 35 minutes -- and will cost just $6 billion to build.
But with the Hyperloop still a dream, for now, high-speed rail is our best option for medium distance transportation. Here, we take a look at a few of the fastest trains in the world.
The Frecciarossa 1000, seen above, also known as the V300 Zefiro and ETR 1000, is a next-generation high-speed train developed by Bombardier Transportation and AnsaldoBreda. The $2 billion, 220-mph train will go into service in 2015, making the trip from Rome to Milan in just 2.2 hours.
Built by Hyundai Rotem, the KTX-II was the first commercial high-speed train developed in South Korea. Seen here along the Gyeongbu line, the rail has been in service since 2010, and can travel at 190 mph.
China's magnetic levitation train is currently the fastest train in the world. Floating above the track on magnets, this train makes the 18-mile trip from downtown Shanghai to Shanghai Pudong International Airport in just 8 minutes, hitting speeds up to 268 mph.
