Japan to Launch Maglev Rail Service by 2025

Only a handful of nations are currently testing Maglev rail technology
Japan plans on having its first magnetic levitation (Maglev) rail system in service by 2025. The trains have a top commercial speed of 310 m.p.h., and use electric-powered magnets to float above tracks. More specifically, floating above the tracks helps greatly reduce the amount of friction between the train and track, helping make the trains go faster.
The Maglevs will replace Japan's Shinkansen "bullet" trains, which have reached their technological and transportation capacity limits. The first Japanese Maglev line will travel between Tokyo and Nagoya.
Central Japan Railway (JR Tokai)
plans on operating the first Japanese Maglev service
, according to Masayuki Matsumoto, JR Tokai President. The company has been testing Maglev cars on a track in Yamanashi for more than 10 years.
Even though a French train holds the world speed record on rails -- 357.2 m.p.h. -- the Maglev holds the current overall record -- a maximum speed of 361 m.p.h.
The only fully operational Maglev line is operating on almost 20 miles of rails in Shanghai. Japan and Germany are currently the nations that have taken great strides to improve Maglev technology. Unfortunately, a German test Maglev train crashed last September, killing 23 people.
As someone who has ridden the Japanese Shinkansen trains before, I am sad to see the famed bullet train forced into retirement -- but am extremely excited to some day ride the first generation of Maglev trains.

Sorry Emma, we may run out of fossil fuels but we will never run out of gasoline, diesel or petrol if you want. All fossil fuels can be manufactured from the chemical up. Often out of waste products out of other industrial processes. So long after the Arab Oil Barons have dripped dry you will be able to gas up your Toyota at the BP.

I believe this is a gross misrepresentation of what the actual process would entail. Sure, matter can neither be created or destroyed and all the stuff, chemically altered stuff, is still in our ecosystem, but this, along with production realities (and their costs) might prove to be a tad more prohibitive than you're assertion implies.... until we have some kind of molecular sequencer I think you're painting a pretty skewed picture.
This is basically suggesting that we shouldn't bother investing in new cleaner technologies simply because we can get away with doing it dirty. Further, it ignores the potential that renewable sources of power may prove cheaper, more abundant, and far more technologically sophisticated in long run.
