Anyway, building that line until 2027 is already a very aggressive schedule, even at Japanese levels of project management. It's impossible to do in half time.
Their first hurdle will be land acquisition. Unlike China, where entire villages are relocated in weeks, a single landowner can throw back projects by decades (see the MacArthur road in Tokyo). I've been to Hashimoto earlier this month - nothing has started yet.

Also, let's not forget that this is the first time that a maglev is built on that scale, even though the tech has been around for years. I'd rather have them take their time to make sure it's fully tested and no corners are cut.

Another constraint they'll face is that everyone will now try to rush their construction projects in Japan until 2020 - hotels, sports facilities, transport infrastructure, tourism ... Japan is about to enter another construction bubble, there will be a limit of available manpower. (Hopefully this will mean a temporary stop on useless dams, village concert halls, regional airports etc. ... ah well, the neverending Japanese pork barrels)
I was talking about a partial opening between Hashimoto and Yamanashi not the full length between Shinagawa and Nagoya.
Second land acquisition would not be much of a problem since land ownership is mostly negated within the greater Tokyo area utilizing the new property law that states land ownership is limited to 30 meters underground freeing space deeper then that. The mountain range JR Central would be tunneling would mostly be state owned so that is not a problem either as long as they pass environmental assessment.
Last the tunneling between Hashimoto and Yamanashi is mostly done since they are going to incorporate the present test site which extends 40Km so there is probably another 50Km to dig which can be done within 7 years.

There is no driver within the train set and will be operated remotely. There are cameras in the front that televise the view to the passengers within the cabin.

If they want to begin support in 2025 they have to begin development around 2013-2014, if they have one season analyze support, which is quite regular for such big tasks.

That indicates they have 6 decades for preparing now.
Acutally a fairly limited schedule, for such a big venture.
Did they set a timetalbe for when they want to begin construction?

Seems strange that it won't run to Osaka before many of its original planners are long-retired (or dead).

In fact, many who remember riding the Shinkansen when it opened in 1964 will likely not be alive when its successor is completed.

There are many great past projects that have taken 10 or 20 years to complete, this one is no different really.

The Gotthard Base Tunnel project is a good example, starting in 1996 and projected to be completed in 2016.

With the amount of tunneling that is required projects like these are always going to take time.

So what are the test objectives here.

They have been testing the technology for decades now, and if 2027 is the opening date for the first section they have another 14 years of testing if they want.

Or will it be 14 years of joy rides.

Until it opens they it will be testing under actual operating conditions with 15 car train set goes under testing in various situation unlike the past years with only a couple of cars as a set.
They will need to test full load test in which all 15 cars are loaded with passengers to see how it works in various situations.

JR Central to raise sound wall height along Yamanashi test track
山梨リニア実験線、防音壁かさ上げへ JR東海

http://www.sannichi.co.jp/local/news/2013/10/07/7.html

Apparently, some of the local residents near the Yamanashi maglev test track’s Ōhara Viaduct (大原高架橋) crossing the Katsura River in Tsuru City have complained that the noise and vibration coming from the track is worse than it was before the extension opened and tests resumed in June. As a result, it was revealed on 2013.10.06 that JR Central will implement countermeasures by increasing the height of the 2 m sound walls by about 1.5 m.

Residents in the Tsubomatsu (坪松) area of Kawamo (川茂) near the viaduct complained to JR Central’s Yamanashi Test Center that the noise and vibrations were now worse, so the railway will increase the sound wall height for about 360 m along the viaduct on the left bank of Katsura River, completing the work in March. The sound wall additions will consist of transparent panels, making it easier to see the trains and accelerating the construction schedule while still reducing the noise coming from the line. In response, the residents want a more permanent solution—namely, noise hoods enveloping the track.

According to the railway, the track segment in question underwent upgrades during construction of the extension between 2011 and 2013, and that there was no change in the noise levels before and after the extension. Instead, they say that housing in the neighborhoods has encroached closer to the viaduct, resulting in the increased perception of noise.

Probably resonance due to elongated train set.

Sonic booms? Maglev is fast but not that fast


Only Blaine the Mono from Stephen King's "The dark tower" series could do that (ca 1,000 miles per hour if I remember correctly).

Just because there is no sonic boom from breaking the sound barrier, doesn't mean all the air being moved doesn't make a sound

For those interested, a detailed explanation of the "tunnel boom" effect and measures taken to lessen it:
