Yeah, from a passenger perspective tunnels are very boring. I remember my first high speed train ride in Italy when it came to tunnels I just sat back and fell asleep.

Why do these noise limiting tunnels have to be concrete? Isn't there some kind of plastic which would do the same job at a fraction of a weight and effort to put together. If there isn't someone should be working on it.

I don't think it will be that bad, just compare it to the the time it takes to ride a long subway line from end to end, and then imagine that you instead of going from one part of a city to another, go between two completely different metropolitan areas which are hundreds of km in between on about the same time. So windows isn't as necessary. Though the lack of views outside the windows might make a lot of people feel the effects of motion sickness due to visual references if they can't make the trains run absolutely perfect.

As a comparison then the more normal Shinkansen line tunnel is about 9.7 meters in diameter (number taken from the Seikan tunnel) where as the Chuo Maglev will have a tunnel diameter of 13 meters [...]
Most new single track rail tunnels in Europe have a boring diameter of around 9.5 m, or something around 8.0 m of inner diameter (so after the tunnel is lined). This means that a double track single tube rail tunnel in Japan is just a little bigger than a single track tube in Europe (where most long double track tunnels are composed by two tubes, while double track tubes have a diameter of around 13 m or more).

Near all Japanese tunnels (except the Seikan, as far I know) also seem to lack emergency exists (except construction adits) and sidewalks between the tracks and tunnel walls, unlike in Europe.

JR Tokai begins building maglev stations

Quote:
Central Japan Railway Co. (JR Tokai) has started to build underground stations at two terminals that will host a magnetically levitated train for service between Tokyo and Nagoya that is expected to begin in 2027, it said Wednesday.

In October, JR Tokai, operator of the Tokaido Shinkansen bullet train service, gained government approval to build the maglev line, which is expected to cost ¥9 trillion ($77 billion). The next-generation train service uses magnetic levitation to carry vehicles and reaches a top speed of 500 kph.

Maglev trains will link Tokyo’s Shinagawa and Nagoya in only 40 minutes, compared with 88 minutes on the shortest route taken by its current bullet train.

JR Tokai started the work at Shinagawa Station in Tokyo’s Minato Ward and at Nagoya Station in Nagoya’s Nakamura Ward after holding safety ceremonies.

The company plans to extend the line further west to Osaka by 2045, shortening the trip between the two major cities to 67 minutes from the current minimum of 138 minutes for a bullet train.

The company plans to start negotiations with some 5,000 land owners to acquire the land for the railway construction.

JR Tokai said it has finished briefings for residents along the maglev train line in 47 cities, towns and villages in seven prefectures: Tokyo, Kanagawa, Yamanashi, Nagano, Shizuoka, Gifu and Aichi.

The company intends to shoulder the entire Tokyo-Osaka maglev train line construction cost. The Tokyo-Nagoya section is estimated to cost a total of ¥5.52 trillion.

In September, the company successfully completed a test run of the maglev train on its test track in Yamanashi Prefecture. The seven-car train moved along on tires and accelerated to around 160 kph, at which point it began levitating and reached 500 kph moments later.

Odd question: will snow/ice be an issue?
That is, will they have to actually go out and remove it if it accumulates (if it could even accumulate, anyways).

If I remember correctly they have an automatic ice thawer.

There are none since there is no driver's cabin. No driver either.

Why are there no windows at the front? I understand they won't be needed because there is now driver. But it would make a fantastic view for the passengers.

When the trains are running I would doubt that there will be any build up, but during nights then these troughs are great for gathering snow if it's windy. But as SamuraiBlue said, there will be snow melting equipment in use. Also remember that the number of sections without a roof is actually pretty small and short, which would mean that the snow isn't really too much of an issue.

I'm pretty sure that it will look the same as any Shinkansen train drivers cabin, but with screens instead of windows. I don't think that the Japanese is ready to go all driver less on these high speed trains just yet.

Well, putting glass in the front will weaken it and makes it harder to form a good aerodynamic shape to reduce the tunnel booms. This due to that is harder to make hard enough glass surface to be able to survive bird(/bat?) strikes at these high speeds that the train will travel in and also have a complex shape to get the aerodynamics right. There are cameras at the front though which image you can show throughout the trains, which makes the feature useful for all passengers in the trains instead of just the first rows.

Will the trains have 3+2 seating or just 2+2 (in standard class)?

2X2, the trains are narrower then the Shinkansen.

Thank you. But is it wise to build smaller trains on a such heavily used corridor? (altghouh the old line will not close, and only Tokyo-Nagoya-Osaka passengers will switch to the new line)
