リニア地上部に「防音フード」設置　山梨区間の8割　JR東海

[...]

県内ではリニアが走行する約83キロの区間のうち、トンネルを除く約27キロが地上区間となる。JR東海は長崎知事らに、地上区間では高さ約8メートルのコンクリート製のフードを設置する方針を説明。車体と空気の摩擦熱を逃すための換気箇所の整備や地盤条件などで、フードを設置できない区間については、上部が空いた高さ約3・5メートルの防音壁で代替するとした。

A translation:

JR Tokai explained to the Nagasaki governor and others that it plans to install an 8-meter-high concrete hood on the above-ground section. For the sections where the hoods cannot be installed due to ground conditions or the need for ventilation to release the heat from the friction between the vehicle and the air, the company said it would use a 3.5-meter-high soundproof wall with an open top.

リニア中央新幹線 改良型試験車両の報道向け試乗会 山梨県内
Press Test Ride of Linear Central Shinkansen Modified Test Train in Yamanashi Prefecture


On October 5, a test ride for the media was held in Yamanashi Prefecture for the Linear Central Shinkansen Line, which has been improved for commercial operation and can reach a maximum speed of 500 km/h.
About 100 members of the press participated in the test-ride event and boarded the improved test train, which JR Tokai has been testing since last year, at the Yamanashi Test Center in Tsuru City, Yamanashi Prefecture. The test vehicle traveled back and forth along the 42.8-km Yamanashi Linear Test Line between Fuefuki-shi and Uenohara-shi, Yamanashi Prefecture, at a maximum speed of 500 km/h. The participants experienced the comfort of the improved vehicle.

According to JR Tokai, the improved vehicle has a 13% reduction in aerodynamic drag, power consumption, and noise level by modifying the shape of the leading edge of the vehicle.

JR Tokai plans to hold a trial ride of the Linear Central Shinkansen for the general public from the 25th to the 27th of this month.

Maglev shows off speed on test-run

[...]
Central Japan Railway invited about 100 members of the media for a test ride on the Maglev in Yamanashi Prefecture, west of Tokyo.

The train reached a speed of 500 kilometers per hour. [...] Company officials say they improved the design of the train's nose section to cut air resistance by about 13 percent. They say that will also help reduce power consumption and noise.

The company says the train line will connect Tokyo and Nagoya in central Japan, in 40 minutes. [...]

But they will never sell it overseas as it cannot carry an overnight container train which makes it uneconomical in big democracies.

Very pretty but will not sell for passengers, it needs an overnight container train to lower daytime fares below planes in a big democracy.
