The original 0-series Shinkansen were retired last year. These were the ones that looked like a bullet. There were trainsets that were donated to museums around the world. There are sets in England and in Japanese railway museums, if I'm not mistaken.
The N700 (Nozomi Service) actually maxes out at
270km/h on the original Tokaido portion of the Shinkansen. This is the portion between Tokyo and Osaka that was originally designed for a max speed of 200km/h. It has a minimum
track radius of 2500m. I believe that these trains are some of the quickest to accelerate as well. A often-overlooked important fact when you are running in highly populated areas.
On a newer portion of Shinkansen, the Sanyo Shinkansen that runs between Osaka and Kyushu they run trains at
300km/h. It has a typical
4000m track radius. It can potentially run much faster in the future.
The newest line, the Hayabusa service on the Tohoku Shinkansen will run at
320km/h. These are the newest E5 series. I'm not sure the track radius, but that line was
planned to run at 360km/h. They just couldn't get the train quiet enough at that speed.
To put this in perspective, China's new 350km/h lines typically have a minimum 7000m track radius. California is planning, I believe, for 6500m.
As alluded to before, part of the reason that trains don't run as fast in Japan is the tunnel boom effect and the number of tunnels that are close to populated areas. Japan has the strictest noise pollution laws (for trains at least) in the world. This combined with the inefficiency at higher speeds and the number of tunnels made faster speeds impractical. Remember, these trains are running every day, all day, sometimes at frequencies of every 6 minutes on some lines.
Japanese companies are one of the parties that are interested in the High speed contract for California.
In my opinion, their experience with earthquakes and their strong desire to export the technology make them one of the better candidates for the California System.
As for the North-east corridor, it probably wouldn't be a bad idea to consider the N700 series, although I'm sure there will be excellent competition for that sector.
Personally, I'd love to see German, Canadian or French technology in the NEC and Japanese technology in the West. The US should try to get a mixture of technology, just as China has done.
