Tokaido Shinkansen - List of tunnels / Line profile

[Reinhard Douté]

Hi all

 

During my recent 2-weeks stay in Japan I timed a number of Shinkansen trains, over the whole of the Shinkansen network but mostly between Tokyo and Osaka. In order to compute actual average speeds I need to know the (relatively) accurate position of a number of timing points, mostly tunnels. For instance, going southwards from Tokyo, there is a tunnel entrance around Kilometer Poste 30.3, another at KP 41,6, and a tunnel exit around KP 70 (this one is very approximate). Can anyone help me on that ? (I also used a few bridges, notably at KP 11,7 ; 280,3 ; 336,3).

 

(ideally, I'd like one day to produce a profile of the Tokyo - Nagoya line - see examples on my website, address below)

 

Best regards

Well, until above happens- could you tell which train(s) (ex. Nozomi No.~) you rode, and the approximate times you took down the note? Looking at a full size timetable (Jikokuhyou) will then narrow down the points, coupled with a good map.

 

As far as I know, the most detailed line profiles for Tokaido Shinkansen can be found in old "untenyosenrozu"- they are sometimes available on online auctions, prices going at 25000 yen.  Also a string diagram (daiya) would likely be as effective, but have yet to see offical ones for the shinkansen lying around.

Hello Mr Reinhard,

 

I am not clear about what information you require.  The line you travelled is called Tokaido Line.  It is the oldest of the shinkansen lines and dates from 1964.  I offer the following suggestions:

 

1. Follow the route with Google Earth and attempt to measure distances;

 

2. Navitime offers basic information here: http://www.navitime.co.jp/railroad/00000110/%EF%BC%AA%EF%BC%B2%E6%9D%B1%E6%B5%B7%E9%81%93%E6%96%B0%E5%B9%B9%E7%B7%9A

 

3.  Wiki offers basic information here: http://en.wikipedia.org/wiki/T%C5%8Dkaid%C5%8D_Shinkansen

 

4.  JR Central Data Book in English, but alas, the information you seek is not there: http://english.jr-central.co.jp/company/company/others/data-book/_pdf/2011.pdf

Hello both,

 

Thank you very much to both of you for this information (including the JRC data file, which is quite interesting). The "string diagram" for which an extract is displayed here

 

http://blogs.yahoo.c...ou/5356315.html

 

is exactly what I am looking for, although I only need part of the information... and I quite willingly admit that a complete one must not be easy to find - it is probably considered as company-internal data.

 

What I'll probably do (unless the data appears to be available) is to interpolate positions using the logs I made. As I travelled several times both ways between Tôkyô and Nagoya, I should be able to sort out most of them on this section.

 

Another option I'll consider is to ask Japan Railfan Magazine if they could help. My name once appeared in that magazine about 10 years ago, in an article "Railtravel distance in 24 hrs" (no. 508, 2003-8).

 

Best regards
