Tenri City wants to join fray for potential site of Nara maglev station
http://sankei.jp.msn.com/region/news...2020002-n1.htm

 リニア中央新幹線の中間駅誘致をめぐり、天理市の南佳策市長は18日、市議会の代表質問で「JR東海などの調査で(中間駅の)候補地を決める段階になれば名乗りを挙げたい」と答弁し、条件付きで将来的な誘致合戦への名乗りに意欲をみせた。

 具体的な誘致場所について、市議から「櫟本(いちのもと)地区は名阪国道、京奈和自動車道のインターチェンジに近く、広大な土地開発が可能だ」などと指摘され、南市長は「基本的に同じ考え」と答弁した。

 答弁後、南市長は報道陣の取材に対し、「県が中心になって進めている事業で、県とJR東海の方針が固まれば、いつでも(誘致に)手を挙げる心づもりだ」と発言。ただ、櫟本地区への誘致については「まだ全然決まっていない」とし、「今の段階で手を挙げるのは拙速と考えており、専門部署を立ち上げるつもりはない」と現時点では慎重な姿勢もみせた。

中間駅誘致には、これまでに県内では奈良、生駒、大和郡山の各市が名乗りを挙げている。
Their proposed location is in the Ichinomoto area, which is close to the Meihan Kokudō and an interchange on the Keinawa Expressway. The new station would likely be co-located with the existing Ichinomoto Station on the Sakurai Line (Man’yō Mahoroba Line), which offers a one-seat ride to central Nara.

JR Central conducting additional boring tests on proposed maglev alignment
http://www.shinmai.co.jp/news/201212...I090003000.php

Quote:
 リニア中央新幹線関連で、県内の少なくとも計13カ所でボーリングなどの調査が行われていることが30日、沿線の関係者への取材で分かった。調査地点はJR東海が2011年8月に示した概略路線(3キロ幅)内の中央付近から南側を中心に分布。県内の調査地点のおおまかな全体像が明らかになるのは初めてで、これらの調査で得られた地質データなどを基に路線の絞り込みが行われるとみられる。

 同社は、来年秋にも公表する環境影響評価(アセスメント)準備書で具体的な路線や中間駅の位置を示す。リニア計画は、14年に予定されている着工に向けた環境整備が進む。

 13カ所のうち、新たに判明したのは飯田市から木曽郡南木曽町にかけての8カ所。飯田市は中央道西側の飯田風越高校敷地内、その西方の同市滝の沢、県営松川ダム西方の黒川沿い。下伊那郡阿智村は小黒川上流。南木曽町内は国道256号清内路トンネルの北方から岐阜県境に近い男滝・女滝付近にかけての計4カ所。このほか、岐阜県中津川市山口(旧木曽郡山口村)の1カ所も調査対象となっている。

 これまでに判明済みの5調査地点は、天竜川の東側に位置する下伊那郡豊丘村南部の2カ所、これより西の飯田市内では中央道東側の同市上郷黒田、風越山の東方、県営松川ダムの南西地点。

 南木曽町内の調査地点のうち、男滝・女滝付近ではボーリング調査に加え、地中で火薬を爆破させた振動で地質を調べる「弾性波探査」用の穴も掘削されている。

 概略路線内での調査地点の分布を見ると、南木曽町内の一部は3キロ幅の中央付近に位置し、阿智村から飯田市、豊丘村にかけては風越山東方の1カ所を除き全てが3キロ幅内の南側に位置している。

 JR東海広報部は、各調査地点が具体的な路線の位置を示しているということではないとしている。



南木曽町吾妻の「男滝・女滝」付近にあるリニア中央新幹線関連のボーリング地点(手前と右奥)=27日
It was revealed on 2012.12.30 that JR Central has been conducting boring tests at a total of at least 13 locations, most of them concentrated along the centerline or the southern edge of the 3 km wide “swath” that JR Central announced in 2011.08. For eight locations, between Iida City and Nagiso Town, this is the first news unveiled to the public about them, while it was already known that tests were being conducted at the remaining five locations. In addition to borings, holes have also been drilled at some of the locations in preparation for elastic-wave vibration tests.

Information on soil conditions and other data obtained in these tests will be used to narrow down the alignment options. The specific route alignment and specific location of intermediate stations will be revealed in the environmental assessments to be published next autumn.

JR Central will restart public maglev rides if Tōkyō wins 2020 Olympics
http://mainichi.jp/select/news/20130...20085000c.html

Quote:
 JR東海の山田佳臣社長は毎日新聞のインタビューに応じ、2020年夏の東京五輪が実現した場合、期間中にリニア中央新幹線を山梨県内の実験線で乗客を乗せて特別運行する意向を明らかにした。リニアは東京−名古屋間で27年開業を目指しており、山田社長は「リニアの素晴らしさを世界に知ってほしい」と意欲を示した。【高橋昌紀】

 特別運行は、五輪に合わせて世界中から訪れる大勢の観光客らの体験乗車を想定。最先端の技術を集めたリニアを体験できる機会をPRすることで、東京五輪の招致活動を後押しする狙いもある。

 山田社長は「五輪を盛り上げるため、リニアを利用できるように努力する。技術的に20年には体験乗車が十分に可能だ」と述べた。20年の夏季五輪開催地は東京、スペインのマドリード、トルコのイスタンブールの3都市に絞り込まれ、9月の国際オリンピック委員会(IOC)総会で決まる。

 同社によると、実験線での体験乗車は07年までに計14万人が参加。延伸工事のため中断しており、実験の状況を踏まえ再開する方針で、時期などは未定。山田社長は「五輪期間中は(実験よりも)優先させる」と強調した。

 実験線はデータ収集などが目的で、延伸工事は13年末に山梨県上野原市−笛吹市間42.8キロが完成予定だ。

 五輪と鉄道の関係は深く、1964年の東京五輪の開幕直前には「夢の超特急」東海道新幹線が開業。2016年夏のリオデジャネイロ五輪に向けブラジルでは高速鉄道の建設計画が進んでいる。

I thought they were going to start rides once the extension of the test track was complete anyway.

Is JR now saying that they will only restart test rides if Tokyo wins the 2020 Olymipics, or are they saying they will open for commercial operation by 2020 if the games are won?

It's just an PR campaign prop although they will need to test the L0 vehicle before starting any public test runs.
With the extension JR Tokai will restart testing such as 15 car running. They will also need to test the terminal speed test in which JR groups are required a 25% buffer from commercial top speed so they need to test the cars at 625Km/h.

625kph nice, do you think they will test beyond this speed, like e.g. 700 or 750kph.

Wheel on steel train advocates currently boasts they can match maglev speeds.
They say the TGV achieved 575kph, almost the same as maglev.

Don't know if they will actually try but it is not difficult since they only need to crank up the frequency inverter up to some thing like 80~90 Htz and maybe put in more electricity.
As for conventional wheel on rail HSR, they'll burn the motor if they force it to far without better cooling. Fastech was already using a water jacket. To go faster means more electricity current meaning more heat. In any case it will be a test type that can never be used for commercial service. Another PR stunt.

But TGV needs 200 km straight to reach that speed. Maglev did 590 kmph on a short 18 km section.

Yes, good point and as Samuruiblue stated it was a modified TGV with special coolant system for the engine.

The maglev will need no modifications, just standard vehicle.

I hope to ride it next year, if they permit joy rides.

There will be a verrrrry long que.

By the way the water jacket I posted earlier was for the Japanese test train the fastech 360 not the French.

Doesn't matter for service , the max acceleration and deceleration is limited by comfort reasons, not by technology. even if Maglev could do a 4G ramp, its better performances couldn't be used in normal service.

For maglev I thought they would be able to go much faster than that.

Isn't China planning in the same speed on wheels with their CRH500? 311mph over ground is still pretty damn fast.

Seriously, the wear and tear involved with running at that speed for commercial operations is just ridiculous, it'd almost mean a maintenance check every 4 runs or so. The technology is just not there yet.

It actually took 70 km to reach that speed. It took 41 km to reach 500 km/h.

I believe during the French run they also cranked up the catenary voltage by 25%, wheel diameter was increased 19% and the catenary tension increased 60%.

And the train was composed by 5 vehicles (2 locomotives + 3 coaches, instead of 2 + 8), the central coach had two powered shared boogies (TGV coaches shares their boogies between them but not with the loco, so N coaches have N+1 boogies, the record train thus had 6 powered boogies out of 8), and so on. The 575 km/h record, like all those above ~400/450 km/h of traditional rail vehicles, were made by modified trains, while maglev's record was made by a potentially series train...

TGV's record was partially demonstration of technology and partially PR trick. The commercial limits for the conventional rail now ar probably somewhere in a 350 to 400 kmh range.

Still the difference in projected operating speed for this project and the current top operating speed for conventional rail (ca 320 kmh) is not as great as I imagined...

Shanghai Maglev does 430km in 188 seconds. That's just 0,06g. With 15 km and 590 kmph max speed that would be 0,9 m/sq sec or 0,09g. Less than metro trains does - 1,3 m/sq sec. So, still quite comfortable.

With 0,9 m/sq sec of constant acceleration it would be more than a 1240 km/h on 70-kilometer section. The Supersonic Train Of course it's just pure numbers. Not taking technologies into account.

Would be nice...I have heard murmerings that they might start an early Kofu/Showa-Kanagawa service in the early 2020s.

And yeah, I thought it was next year public test rides were to start again

My point is that conventional trains are already able to have accelerations of 0,97 m/s2 in actual service (1,3-1,45 in tests); maglev probabily could have much bigger accelerations that however could not be used for comfort reasons.
