Hyper Fast Trains

Another Elon Musk backed company, Hyperloop is a high-speed underground transportation system that is currently being built and tested in America. The first route planned will go from Los Angeles to San Francisco. Another route is planning to go from New York to Washington D.C. in 29 minutes rather than the 2 hours 56 minutes it takes at the moment. 

Hyper-fast trains that go underground and underwater could revolutionize not just public transport, but international travel too. Imagine being able to speed from one country to another at the same time.
