Kodama aren't necessarily shorter. For San'yō Shinkansen, yes, that's the case, but Tōkaidō Shinkansen is all 16-car trains, regardless of stopping pattern.

Kodama dwell time when being passed by faster trains varies... On Tōkaidō Shinkansen, it's 4-6 minutes, but San'yō Shinkansen is less consistent, and the dwell times can range anywhere from 4 to 11 minutes.

Perhaps to shed a bit more light on the issue of capacity at Tōkyō Station post-Hokkaidō Shinkansen, the first phase between Shin-Aomori and Shin-Hakodate is being built for 10-car trains.

Strange that they haven't built for 12 cars north of Hachinohe, or even 12 cars north of Morioka (if the rest are 10 cars). But then again, most (all?) new trains are only 10 cars, which can be extended to 17(16) cars with an additional mini-Shinkansen.
So why even bother with building 12 car stations when you never would use it, since the rest is only 10 cars?

I did measure the stations in Google earth but since none of the stations north are visible on (only construction) then I guessed that they would be 12 cars like the ones before...

Yeah, the Google Earth aerials don't get updated very frequently. They don't have Kyūshū Shinkansen either, and the image quality is not so hot.

Regarding the 10-car thing, yeah, they're probably just being conservative and building only what they know they will need. I suspect they are still considering the potential that they may need extra capacity in the very long-term future, though... If you look at Kagoshima Chūō, for example, this was originally built as an 8-car station, but they can extend it to 16 cars (400 m) by extending out over the station plaza and adjacent road. Would require some work, but certainly not impossible:

Are the stations on the Nagano Shinkansen already modified for the 10 car E7?

Will they cover the ends of the platforms or will they just install more platform doors and leaving it all open?

There's nothing on the Web, but given the weather and the expected passenger flow at Nagano, it makes sense to cover the new sections of platform. It's probably too early for an announcement, though, since there's no real work involved (platforms are already built to 12 cars)... Maybe next year we'll hear something about it.

The Shinkansen 300 series will have last run on 03/16.


To commemorate it's graduation the last set has gotten some special stickers.






The train will run some Nozomi services in February and some special services in March. On 03/16 it will run Nozomi 329 from Tokyo to Shin Osaka.





After 20 years of service it's the end of this classic trains, leaving only the 700 and the N700 on the Tokaido Shinkansen.

100 series will be withdrawn from service in March 2012 too.
When 200 series will be withdrawn?

Will they be taken apart, and parts recycled, or will they be retrofitted and sold to other countries?

No, they won't be sold as secondhand trains... JR hasn't done that with any Shinkansen. Besides, most of the countries receiving donated trains from Japan are still developing, and don't have any high-speed rail to speak of... I don't think they would have much use for Shinkansen trains.

A 20 year old train is only half-life...why do they replace them?

The Tokaido Shinkansen Line is the most heavily used high speed rail line in the world. More people ride this single line than people ride high speed rail in France (all lines)!

Irrelevant - Shinkansen and TGVs run a similar distance per set per year. They certainly aren't separated by a factor of two.

To answer Coccodrillo - the Japanese do not think trains should run for 30-40 years. They are all typically replaced much sooner than anywhere else. I assume the logic is that the last 20 years are often costly in terms of maintenance, but I am not sure precisely why.

It's actually just 14~15 years for individual trains, the oldest sets that came into service in 1992 where withdrawn from 2007.

You need to differentiate the technical and the economical life cycle of these trains. Technically they can be refurbished and used like other older series on the Sanyo Shinkansen line for Kodama services for some more years. They will need enough work since they have been used extensively on the Tokaido Line. But there's no need for this at the moment because of fairly recent introduction of the newer 500 series on these services on the Sanyo line. The introduction of the N700-7000/8000 on the new Sakura and the Mizuho services since the Kyushu Shinkansen opened also reduced the need to give the 300 series a new life.

If you look at the economical life cycle it's pretty clear that these have earned their money. The profits of the Shinkansen are big enough to just buy new trains every 15 years. The new N700-1000 series that comes into service this year will already send some of the oldest 700 series that are in service since 1999 to the scrapyard in the next couple of years. These new trains are faster in max speed and better in acceleration and breaking then the old 300 series. This will mean faster timings and maybe even an extra train in the already very busy schedule. It's basically the only way to improve the service on the line since there won't be many new infrastructural improvements to the line now they are building the Chuo Maglev.

yeah exactly. without a mid-life refit the life-cycle is shorter, which in turn allows quicker evolution of the trains, their performance and therefore the service. in highly profitable areas of engineering it is almost foolish not to buy new improved tech regularly. after all if profits drop they can shelve the new purchases and refit old trains instead. cant see that happening any time soon in japan though.

That's exactly why they would need high-speed trains... because they don't have any yet

If you haven't got any high speed lines there's no reason to buy high speed trains, and if you can afford to build a high speed line you can afford to buy new trains for it.

If you only have cruddy old 120 or 140 km/h trains, less old and less cruddy Japanese trains that you run at say 160 or 180 km/h might actually be a good thing.

The problem is that the Shinkansen is such a specific system, with trains designed specifically the Shinkansen lines that it will be hard and therefor expensive to adapt them to be used on any other line.

Not to mention purchasing new trains keeps a lot of people in the Shinkansen industry employed.

Similar to how Japan imposes expensive car inspections on older cars and have domestic-only Kei cars. (Very few cars older than 10 years old in Japan) It encourages people to continuously have newer cars on the road for two reasons:

1 - Overall, the roads are safer with a newer fleet on the roads.
2 - Stimulates the car industry. (People buy more cars because, Hey, kei cars are not that expensive)

A quick question:

The Tokaido Shinkansen is regularly delayed by a few minutes in winter due to snow in the Maibara area, which is a pretty common occurence due to its proximity to the Japan sea and higher elevation. However, the Tohoku Shinkansen *seems* to deal perfectly well with snow most of the time.

Can anyone tell me what measures thay've taken on the Tohoku Shinkansen as opposed to the Tokaido?
And if there are major differences, why? Surely JR central has to pay out quite a bit to people who are delayed in winter?
