Nope. The plan is to add more stops and expand the Hikari and Kodama service. There's just too much demand for passenger traffic on that corridor. Freight service was originally proposed before it opened in 1964, and there were small-scale mock-ups, but the passenger traffic was immediately too high and has remained there ever since.

Not only that, but also bare in mind that the maximum axle loads on Shinkansen routes are very low. A loaded E4 has a maximum axle load of 16t, while most other types are 13t and under. Good luck trying to construct a train with such low axle loads still having a reasonable pay load capacity. You could reduce car length, but then you will probably run into the ton per meter limits imposed.

How does the axle load of TGV mail compare?

The German wiki on the TGV postal mentions a pay load of 10,5t per car and an unloaded axle load of 13,3t. Given that due the Jacobs bogies every car effectively rests on 2 axles that would give a loaded axle load of 18,5t.

Really, in 1964, JNR had a project to operate freight trains at Tokaido Shinkansen. The mock-up shows us that "Freight Shinkansen" EMU's would be very similar for modern M250 EMU's.

Bringing over a discussion from the JAPAN | Railways thread:

While the 500 Series Shinkansen was the first Shinkansen trainset to achieve 300 km/h on certain stretches of the San'yō Shinkansen line, it was also exorbitantly expensive to build. That's why only nine complete 16-car sets were built. In contrast, using much of the tooling from the 300 Series Shinkansen, the original 700 Series Shinkansen had a top speed of 285 km/h but was much less expensive to operate--hence the reason why 91 complete sets were assembled. And the 700 Series are being slowly replaced by the N700 Series, which has 153 complete trainsets built (and new ones are still being built to the N700A standard), which can go as fast as the 500 Series but could do that for much longer periods of time (N700's going 300 km/h as common sights west of Shin-Osaka Station).

I do think a successor to the N700 is coming, though. I can imagine a "-10" Series Shinkansen with the same top speed as the N700 Series, but with an E5-like nose to reduce drag and the dreaded "boom" noise out of tunnels even further, more efficient drive motors with faster acceleration (needed for the more frequent-stop Hikari and Kodama service), lighter bodies, and a better suspension derived from the E5 and E7 Series. I wouldn't be surprised at all if the new trainsets are designated C10 in JR Central service, W10 in JR West service, and K10 in JR Kyushu service.

There are all Shinkansen data (in Excel format).

More recent data would be appreciated, especially JR Kyushu, which seems not published annual report.

Passengers and Passengers-kilometers world data, and explanation of the fact that the operators and the UIC count -in some cases- the number of passengers on high-speed trains, not on high-speed lines.

N700S

JR West announced today the introduction of the new N700S (S for Supreme) on the Tōkaidō and Sanyō Shinkansen by fiscal 2020, replacing the 700 series.

New train modernizes the current "Aero Double Wing" with the new "Dual Supreme Wing".



First prototype 16-car N700S is announced to be released by march 2018.

More details:

Japan railway plans lighter, less power hungry bullet train

NAGOYA -- Central Japan Railway will in about four years introduce a new bullet train that will be lighter and consume 7% less electricity than the latest varieties in operation, the company announced Friday.

The N700S "is an innovative rolling stock that is a product of rapid [technological] advancement," President Koei Tsuge told a press conference that day. Although he did not specify the investment amount, making it into the company's mainstay bullet train would mean spending well north of 100 billion yen ($977 million).

...

Prototype N700S carriages will be completed by spring 2018 with service to begin starting in the fiscal year ending March 2021.

Top operating speeds will clock in at 285kph on the Tokaido line, unchanged from the N700A, the latest version introduced in 2013.

A set of 16 N700S cars will weigh 20 tons less than a train consisting of the same number of N700A cars and nearly 300 tons less than the 0 series, the first shinkansen model. The weight will fall below the 700 ton threshold for the first time. The lead car comes designed with edges that will reduce the amount of noise and improve aerodynamic performance.

The weight reduction is the fruit of joint technological development efforts launched four years ago with Toshiba, Hitachi and two other major electronics firms [Fuji Electric Co. and Mitsubishi Electric Corp.]. Drive systems at the bottom of carriages will be miniaturized through the use of silicon carbide-based power semiconductors.

All seats will have electrical plugs so passengers can charge mobile devices. The carriages will also come equipped with small, large-capacity lithium-ion batteries so that people can use bathrooms even during power outages.

The N700S can accommodate trains of various lengths [8, 12 and 16]. The company, better known as JR Tokai, is providing technical support for a shinkansen project in Texas and is pursuing orders to replace rolling stock in Taiwan. Both places utilize shorter trains than what is seen on the Tokaido line, and the N700S "can be used in Texas and in Taiwan," said Tsuge.

Where are the headlights of N700S trainsets?

With the Asterisk mark it states that the position of the headlights are still under consideration.

I have this feeling that the new N700S will probably have an improved air suspension system to allow the train to go from the level to tilt mode and back faster so it can take the curves on the Tokaidō line east of Mashima Station on faster. I wouldn't be surprised the N700S could be certified for speeds as high as 300 km/h on the Tokaidō line between Shizuoka and Toyohashi and Maibara and Kyoto.

To get trough corners quicker without impeding passenger comfort you would need more tilt. However, they can't increase the tilt much further, because they use the suspension for tilting. Additionally, because of the rectanglar body shape, especially the Tokaido, with it's narrow tunnels and narrow track spacing, may not have enough clearance to allow for extra tilting. For comparison take a look at the Pendolino. Its upper body is more trapezium shaped to stay within the loading gauge while tilted.

I like this idea. Since they mentioned it I guess that this is not already the case for existing trains?

It depends from model to model.

For the N700 electric plugs are available to all green seats and the window seats and the seats in the front and back wall.

The 700 electric plugs are available to the seat at the very front and back on the wall but some cars does not have any plugs at all. Same with the 800.

E6 & E5 same layout as the N700.

As for the E3 & E2 it depends on when the cars were manufactured so you need to know the car lot number to see if they are equipped or not.
