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.
Belgium's HSL-1 has a top speed of 186 mph and can make the trip from Brussels to Paris in just 90 minutes. It has already been running for 15 years.

South Korea's KTX 2
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.
Germany's ICE 3, Class 403
Germany's ICE 3 Class 403 high speed train which travels at 199mph and is built by Siemens Bombardier, is seen here traveling along the Frankfurt-Cologne line near the Oberhaider Wald Tunnel.

France's high-speed train TGV Réseau has a 236 mph capability, but it's normally limited to running at 199 mph.
Japan's Shinkansen E5
Japan's pointed Shinkansen trains, built by Hitachi Kawasaki, have a top speed of 275 mph, and regularly travel at speeds of up to 200 mph.
China's CRH380A bullet train
China's CRH380A bullet train is seen here in the Hongqiao Station on the Beijing-Shanghai railway. The CRH380A topped out at speeds of 302 mph and regularly runs at 217 mph.
The CRH380A is manufactured by CSR Qingdao Sifang Locomotive and Rolling Stock Company, and can carry up to 494 passengers along its routes from Shanghai to Nanjing and Shanghai to Hangzhou.
Shanghai's magnetic levitation
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.
