Talk:List of tunnels in the United Kingdom

message: The http://www.sheffieldhistory.co.uk/forums/index.php?showtopic=7453 website has an article that first appeared in the Transactions of The Hunter Archaeological Society and is reproduced by kind permission of the Society. The tunnel also gets a mention on the http://research.ncl.ac.uk/hydroinformatics/rbhd/derwent/upper.html page and the  http://www.jnbentley.co.uk/345/rivelin.html page (but they call it the Dewent Tunnel; I have emailed them with a suggestion they correct their page). It deserves a mention in the list, but where should it be placed? It starts in Derbyshire but the outfall is in South Yorkshire. I am sure other tunnels connect different counties. Is 'county' a good choice for a table column?

thread_title:  What about the 7,652 yards long Rivelin Tunnel? 

message: I've added (above) all railway tunnels greater than 1 mile, according to my own data, and put the distances on the article page for tunnels already listed. This may disagree slightly with distances quoted within the articles - I haven't checked these. I've done a bit of tidying, and tried to get a consistent presentaion, however this is crying out to be put in table format, if anyone has the knowledge and time to do this. Sadly at the moment I have neither!--Tivedshambo (talk) 21:01, 20 June 2006 (UTC)

message: If nobody objects i'm going to change the 'transport type' to just 'type', as some of the tunnels are used for telephone exchanges and air raid sheleters... Williams119 (talk) 22:49, 2 March 2009 (UTC)

message: The article is now flagged as incomplete. I was minded to make a new template saying "singularly incomplete". All the stuff above should be in the article or in a sandbox, not in this Talk. "history" suggests some of the lists have sat here for a considerable time.--SilasW (talk) 18:10, 24 June 2009 (UTC)

message: If nobody objects, I propose separating put metric and imperial measures.  The metric column will be sortable and will be strictly in metres, the imperial will be non-sortable and will have miles or miles and yards as appropriate. Martinvl (talk) 12:50, 25 March 2010 (UTC)
thread_title:  Separate metric and imperial columns 

message: I've been making some changes to this page, but it raises some issues in my mind to make the page both accurate and useful.
*It needs to be definitive. I have found some gaps, but I suspect there are many more.
*The fields need populating
*County names are innaccurate, especially for Wales
*Spliting into the constituent nations would aid navigation and checking
*We need a way of dealing with tunnels which quite frequently have ends in different counties
I will continue to update. I have a separate list of tunnels that I will compare. welsh (talk) 11:02, 11 April 2010 (UTC)

message: I've been playing with coords on this article, as has Andy. Couple of questions: I decided to tag a London Heathrow tunnel with two coords, one for each portal. And then Norwood in Derbyshire with 3 coords. And I'm using small coords, AndyM is using normal sized (and has decided views on these things ;). What do we make of either of these things? If we have tunnels that are difficult to figure out from a centrepoint, should we use the two portals and maybe the centre point? Or does that make the page too lengthy? But then, couldn't we find three short lines of text to describe each tunnel? Is small an accessibility sin, and if so, why? Infoboxen seem to have smaller text in them. --Tagishsimon (talk) 23:04, 21 December 2011 (UTC)
replies: text: If we are going to have coordinates, then we need to use a small script - I don't thuink that anybody will actually read the coordinates, but they might well click on them.  I agreee that the number of coordinates poses a problem, possible the mid-point between the portals (which is not neccessarily the midpoint of the tunnel - the Hindhead Tunnel for example follows a 60o arc. One could of course log the midpoint and either the approximate direction of the portals (N,S) or the direction of the tunnel in the range 0o to 180o. This would enable the user to find the portals using the midpoint info. Martinvl (talk) 07:49, 22 December 2011 (UTC)

message: The longest tunnel on the Merseyrail metro runs from Birkenhead Park under the river, through Liverpool's centre and south to Brunswick station. It must be between 5 to 6 miles long. 
The Victoria/Waterloo tunnel is over 2 miles long while the Wapping tunnel of 1829 is 1.25 miles long.  The article is wrong.  — Preceding unsigned comment added by 94.5.105.195 (talk) 08:22, 11 May 2016‎ (UTC)

message: Given that some of the tunnels on this list are... not very long at all - and aren't worthy of articles of their own - what do people think of a minimum tunnel length of criteria for inclusion? I quite like following the info at the top of the page (0.1miles/160m), but I think I'd be okay with a minimum of 100m. 
(Obviously tunnels that are well referenced and verified enough for an article but are shorter than this length would remain in the list) What do people think? Turini2 (talk) 23:21, 6 December 2021 (UTC)
replies: text: Well, I gave it 2 months - removed any tunnels shorter than 100m that do not have a valid wikipedia page. Turini2 (talk) 16:18, 4 February 2022 (UTC)

message: 'County' as a heading is too ambiguous being less specific.  Will change to better fitting location. 188.213.137.9 (talk) 11:03, 8 March 2024 (UTC)
replies: text: Following comments by @Ehrenkater, I think that's a reasonable change. I would not be supportive of changing locations to exact places (e.g. Birkenhead) rather than general regions, counties etc (e.g. Merseyside). That detail would sit best in the individual article about the tunnel in question. Turini2 (talk) 16:40, 8 March 2024 (UTC)

text: Ideally, it would be informative to show the exact location in the table rather than just the county (especially in parts of the UK where the county has changed several times and there are principal areas, regions etc.) However I realise that
* that would be quite a lot of work;
* in some cases, there would be no obvious location to put in.---Ehrenkater (talk) 11:19, 9 March 2024 (UTC)
