Talk:Seikan Tunnel

message: In case you were wondering, the DYK was "...that the Seikan Tunnel (connecting the islands of Honshu and Hokkaido in Japan) is currently the longest railway tunnel in the world, and will be until the new Gotthard Base Tunnel (Switzerland), with a length of 57 km (36 miles), is opened?--Commander Keane 13:23, 22 May 2006 (UTC)

* Grouting procedures
* Constructions procedures (steel ribs, cross section selection)
* Images of the cross sections, top and side views of the entire tunnel

thread_title: Ideas for expansion

message: Hmm.  JRTR says the station was "demolished", but ja-wiki merely states that it's no longer served by scheduled traffic (定期列車の停車がなくなる).  Who's right? Jpatokal 16:27, 18 May 2006 (UTC)
replies: text: I am no tunnel expert but from what I have seen and learnt about tunnel building and mining I think it is more or less obvious what they have done. When working in long tunnels or deep mines usually they have some wider areas and/or side rooms where they can store, park and service equipment and vehicles, have a lunch room and restroom for the workers and so on. Usually those side rooms have their own shafts/elevators to the surface etc. My guess is that both those stations had that purpose during the original building of the tunnel. And that they now removed/demolished the contents of the Yoshioka-Kaitei station to make room to once again use it as such a service side area. --David Göthberg 03:07, 11 June 2007 (UTC)

text: Oh, I just noticed that the Yoshioka-Kaitei Station article says the same. It says: "the station was shut down and to be used as storage space for Hokkaidō Shinkansen building materials." --David Göthberg 03:16, 11 June 2007 (UTC)
thread_title:  The fate of Yoshioka-Kaitei 

message: Am I seeing things correctly - in the diagram it shows the tunnel sloping downwards and then upwards - I've never seen a tunnel like this before.  How would the passengers keep their drinks/food on the table and prevent them from spilling if this was the case?  Seems like it would be an uncomfortable journey...

replies: text: The diagram is just compressed lengthways for clarity. The tunnel is built to shinkansen high-speed line standards, so the gradients aren't even noticeable in practice. --DAJF (talk) 12:45, 24 June 2008 (UTC)
thread_title:  Tunnel is on an incline?!  What the?? 

message: It looks really strange to spell out such common units as km, especially where two English spellings exist (“kilometer“ or ”kilometre”).  Even the MOSNUM allows us to use the abbreviation “km” here.  I suggest to revert the last change. --Bk1 168 (talk) 05:12, 8 September 2010 (UTC)

message: Seeing no edits on the article or here since the great earthquake of March 11, I presume "no news is good news" re. the effect on the tunnel?  If any reliable information is available, it seems it would be good to discuss it here and possibly include it in the article.  Thanks.  Wwheaton (talk) 14:37, 13 March 2011 (UTC)

message: Had there been any such rail-traffic before completion? Wasn't there only sea there? — Preceding unsigned comment added by 5.71.127.36 (talk • contribs) 16:23, 14 August 2014 (UTC)
replies: text: It probably needs to be added to the article to clarify the wording, but before the tunnel opened, trains were loaded on ferries. --DAJF (talk) 23:24, 14 August 2014 (UTC)
thread_title: Once the tunnel was completed, all railway transport between Honshu and Hokkaido used the tunnel.
