Talk:Tunnel

message: Project Gutenberg has "Tunneling: A Practical Treatise" by Charles Preleni with public domain full text and illustrations.  Many of the illustrations would work for this article.  A description of the history of tunneling, construction process, finding the center line, how to join up a tunnel dug from each end, ...
would be helpful for this article.  Adding a link to the public domain book would help.   — Preceding unsigned comment added by 2600:1700:D591:5F10:BC70:D931:6D17:23A5 (talk) 04:53, 15 August 2019 (UTC)

message: The Jingtai Expressway article reports that plans are under consideration for a road link between Beijing and Taipei, including a possible tunnel under the Taiwan Straits from the Chinese mainland (likely Fujian province, according to the article). If this is confirmed, surely it might be notable on the topic of tunnels. --Dpr 16:25, 5 September 2005 (UTC)

message: Can anyone add more info on the possible plans of contructing a tunnel and/or bridge across to the other side elsewhere? I am quite curious as to whether any steps have been taken to decide to build infrastructure links across the:
:*Strait of Messina
:*Fehmarn Belt
:*Cook Strait
:*Palk Strait
:*Strait of Tartary
:*Irish Sea
:*Strait of Bonifacio
:*Surigao and San Bernardino Straits
:*Hainan Strait
:*Strait of Georgia
:*Kvarken
:*Chacao Channel
:*Strait of Magellan
:*Bering Strait
Anyone with inside knowledge on any of these? I've posted similar requests elsewhere. Gruesome Twosome! 8v] //Big Adamsky 10:03, 13 January 2006 (UTC)

message: Wanted to insert the following, but the current article is not yet receptive for history/social sciences.
"In Victorian times, it was anticipated that going through a dark tunnel in a train at high speed (30 mph) would be such a shocking experience that people would come out the other side irreversibly damaged."

thread_title: The tunnel experience

message: This article could be made more useful to those studying transportation systems if it included a section detailing tunnel economics versus economics of other transport systems such as surface roadways, surface trains, elevated railways, etceteras...   Several cities have had costly underground commercial transportation tunnels built (e.g. London Post Office Railway and the very lengthy Chicago Tunnel System) that subsequently closed due to poor economics.  What changed between conception, construction and closure?  Were the original economic analysis faulty, did other transportation systems become more cost competitive, or did the original tunnel system contract customers cease operations (such as discontinuation of coal deliveries in Chicago after the advent of gas heating)?  In an increasing congested urban environment such economic analysis would benefit those studying, planning or implementing urban transportation systems.

message: 'Railway tunnel' and 'Rail tunnel' should not redirect to this article. They should have their own article. For example, Channel Tunnel. 'Tunnel' is too broad. WinterSpw (talk) 16:15, 23 March 2008 (UTC)
replies: text: I don't see the need. Bridges and tunnels can be classified many ways, including age, continent, type of barrier crossed, materials, size, and traffic carried. The way this article classifies them is by construction method, and each type is used for more than one kind of traffic. There's no more need for a separate narrative about rail tunnels than for one about South American tunnels or road tunnels or stone bridges or 18th century bridges or tunnels between 5 and 10 meters wide. At most, someone might seek mere list articles, broken down in these various ways. Jim.henderson (talk) 13:54, 29 March 2008 (UTC)

thread_title:  Multiple tunnels 

message: :Some civic planners define a tunnel as 0.1 miles (0.16 kilometers) in length or longer, while anything shorter than this should be called a chute.
This isn't sourced and it isn't clear how wide spread this definition is. Given that the definition is rather adhoc in any case, it seems more likely to me that someone in a country where metric predominates would use some like 150 metres or 200 metres rather then 160.

thread_title:  Definition 

message: I don't mind any WikiProject taking an interest in any article however tenuous the relation between the project and the subject matter at hand. So for WikiProject Bridges to adopt this article I have no objection. It's a little odd, that's all. However, for the article itself to be categorized into :Category:Bridges I am concerned, and all the more so since there is not one word in the article which discusses this. If there is a tradition among architects and transportation planners to define a tunnel as a bridge, then that must be detailed and documented. If not, the category should not include this article.
I became aware of this situation as I was attempting to see if a tunnel could be categorized by year of opening. If the above connection can be made, perhaps it would be prudent to rename the :Category:Bridges by date to :Category:Bridges and tunnels by date? __meco (talk)
:I only tagged it because of the categorization. I will note, however, that there is no firm line between the two; a cut-and-cover tunnel, for instance, can be considered a bridge, as can a tunnel through a huge railroad fill. --NE2 15:47, 16 August 2008 (UTC)

thread_title:  Removed from list 

message: The types is important and distinction should be made. A water tunnel is different to a canal tunnel which is different to a rail tunnel which is different to a road tunnel, which requires large fans to operate properly. 
Then a distinction should be made if the tunnel runs under water and the construction of generally different to above water tunnel.
Then the construction method, which is different in many tunnels.
Then there is the first, oldest, oldest still used, longest, pioneering, etc, of each type.
It is all relevant, they are all are worthy of note.  Rail tunnels I find important as the railways shrunk the world.

If someone has information about the approximate costs associated with each construction method, that would make an excellent addition to the article. (That's what I was after when I came here, actually.) 217.158.111.130 (talk) 10:34, 14 October 2009 (UTC)

thread_title:  Deleted photo 

message: The lead picture "Underground tunnel for heatpipes between Rigshospitalet and Amagerværket in Denmark" is a bad choice: dazzlingly psychedelic/symmetrical, unfamiliar visual material, not a good way to convey a concept to a reader the actually needs to learn what "tunnel" refers to.
The picture
"A short section remains of the 1836 Edge Hill to Lime Street tunnel in Liverpool. This is the oldest used rail tunnel in the world. A tilting train passes through the tunnel."
is bad and should be removed; contrary to the caption, this is picture of an open above-ground station, not a tunnel.
Some of the other pictures currently in the article are OK, but none of them are good introductions to the basic general concept.-96.237.79.6 (talk) 12:09, 14 September 2010 (UTC)

message: A fork article about tunnel construction had been created using contents from the main Tunnel article. In User_talk:ThurnerRupert#Tunnel construction, the creator suggested tunnel construction could be expanded. I'd like to bring this to the interested parties about this article for discussion and views on action. For now, I have redirected the newly created duplicate article to the corresponding section in the main article. pseudonym Jake Brockman talk 09:55, 30 July 2017 (UTC)
replies: text: I believe that tunnel construction is a vast enough subject which deserves its own article. A WP:SPLIT from Tunnel is a good start, then construction techniques can be briefly described in the main article per WP:SUMMARY. — JFG talk 10:05, 30 July 2017 (UTC)
replies: text:  agreed, I have reinstated the tunnel construction fork. The main article will need editing to shorten the section in order to resolve the duplication as per WP:SUMMARY and WP:SPLIT. I noticed that there are 3 main types mentioned in the intro to that section, but then the article goes on to summarise many more. I'm not an expert in the field, so didn't want to arbitrarily delete and move stuff around. Any thoughts? pseudonym Jake Brockman talk 13:13, 30 July 2017 (UTC)
