JR Central resumes running tests with new L0 mass-production unit

On 2013.06.03, JR Central invited members of the press to see the first L0 formation (a five-car consist, but final formation will be 12 cars long) towed out to the test center in Tsuru City, Yamanashi Prefecture and run at low speed (10 km/h) on the test track to check clearances and safety. Levitation tests will begin sometime this month, gradually increasing the speed until 500 km/h running tests are reached in September. Once the test track is extended to 42.8 km, the maglev will be able to run at the top speed of 500 km/h for about two minutes.

Do you think they will go for any new speed records?

600 or 700km would be pretty cool.

They need to since JR has an internal safety cap of 25% of top speed. So to enable to run at 500Km/h commercial speed, they need to test the train if it can reach 667Km/h for internal certification.

If trainset is 125m long then it runs about 225 kmph.

Looks like it's caught some fire on board judging by body condition @2:40.

If you look at the back end, it has the same maks in the exact same spot, it's probably ventilation of some sort that gets evacuated there.

I believe they still have the diesel generator on board. It is suppose to be replaced with a electro-magnetic coil pick-up to feed the required electricity.

The profile of the train seems unusually boxy and angular, not what I'd expect from something intended to go 500km/h.

According to JRC, around 178 million dollars US per kilometer but this includes tunneling. JRC did a cost comparison with conventional Shinkansen construction on the same route and came up with an estimate of 146million dollars US per kilometer or 22% more per kilometer for maglev.

I believe JR maglev will be driverless since the speed is beyond human reflex.

It doesn't matter, so long as it is smooth in the direction of travel, which it is.

Well for most of the time when airplane speed is above 500km it's driverless too. Shanghai Maglev is also driverless, although it has a computer terminal to monitor train conditions.

Maglev noise hoods will include view portals
リニアの車窓、パラパラ漫画式に JR東海、景色と両立試験へ

http://www.nikkei.com/article/DGXNZO...3A710C1CR8000/

Most of the line will be underground, but on at least some daylight sections, JR Central will also be installing noise hoods to keep noise levels within the required thresholds (70 to 75 dB). Of course, this means that passengers won’t get to see much of the outside, but JR Central says they will be considering embedding small glass windows into the walls of the noise hoods at standard intervals, such that passengers inside a maglev train passing at full speed (500 km/h) would be able to look outside and see the scenery change one step at a time similar to a パラパラ漫画 (flip book animation). They’ve already installed this design on a portion of the maglev test track in Ōtsuki City.

Some of the local governments want the hoods to be made of transparent materials like plastic instead of concrete, but JR Central says that those designs wouldn’t meet the noise insulation and durability requirements.

But the reason is not " because the speed is beyond human reflex". Some jets go mach 3, and they have human 'drivers'.

A jet pilot doesn't have to react to situations like a bear on his track.
