The World's Fastest Train Will Float on a Cushion of Electromagnetism

The fastest train in America, the Amtrak Acela line running from Boston and DC tops out at 110MPH. Sure, that's way faster than taking a Greyhound, but pathetically pokey compared to the 311MPH bullet of the Mag-Lev train currently being developed by Japan's JR Tokai.


Dubbed the Series L0, this prototype commuter train will reportedly carry up to 1,000 riders in 16 cars per trip. Like other bullet trains, the L0 relies on magnetic levitation—whereby an object is suspended using nothing but magnetic fields—for its propulsion and support. While Mag-Lev systems are more technically challenging and expensive to build than conventional train systems, their unique magnetic ability translates into a quieter, smoother ride for passengers and significantly reduced maintenance costs for the train operators. What's more, because there is no friction between the train and the track it travels over, Mag-Lev trains can accelerate to speeds far beyond what conventional, wheeled locomotives can obtain.

When the train enters service in 2027, it will travel between Tokyo and Nagoya, two of Japan's busiest transportation hubs along the famous Chuo Shinkansen Line, which already carries much of the country's high-speed rail traffic. The 216 mile trip from Tokyo to Nagoya will drop from 90 minutes to just 40. Most of the trip will occur 40 meters underground in specially-built tunnels. By 2045, authorities plan to expand the route all the way to Osaka—at 500KPH the Tokyo-Osaka transit time will just over an hour for the roughly 500km trip.

15 years may seem an interminably long time to wait for a speedier ride but Mitsubishi and Nippon Sharyo have already begun construction on 14 pre-production models and a five-car test train is expected to hit the tracks by next year.

I'm sure this is crazy expensive to build. Will someone please enlighten me as to why building this is more cost effective than expanding or building new airports that would provide low-cost air travel?

I realize traveling on a plane can be a bit of a pain, but a 1 hr flight from DC to BOS sure beats a 7+ hr Amtrak trip for now, and I'm not sure the convenience of train over air travel negates the extreme cost of building this thing...
