Talk:Tunnels underneath the River Thames

CTRL Tunnels
Twin tunnels for high-speed trains have been constructed between Ebbsfleet in Kent and Purfleet in Essex as part of the Channel Tunnel Rail Link. I was under the impression the tunnels are between Swanscombe and West Thurrock. Can anyone confirm? --LiamE 09:52, 1 March 2006 (UTC)

The tunnels surface in West Thurrock and the track then runs into Purfleet which is the next settlement. —Preceding unsigned comment added by 79.66.152.206 (talk) 16:15, 13 November 2008 (UTC)

The Dartford crossings are not the only crossing point between central London and Dartford - although they are the only fixed link. Isn't there also a prosed bridge somewhere in east London? Thryduulf 14:22, 9 March 2006 (UTC)
 * this article is about tunnels only &mdash; Martin (MSGJ · talk) 17:44, 6 July 2021 (UTC)
 * Yes. I'm not sure at this distance quite what my comment was complaining about, but the article has changed somewhat in the last 15 years and there is no current claim that there are no crossings between central London and Dartford so it is no longer relevant.

 * Yes I was aware of that, and we are both still around! Here's to the next 15 years ... &mdash; Martin (MSGJ · talk) 19:44, 6 July 2021 (UTC)

Additions
The new tunnels for the channel rail link east of the Dartford Tunnel need to be added to the image and the list Plus the Dartford_Cable_Tunnel just west of the Dartford Tunnel also needs to be added. htmlland.net 10:47, 15 September 2007 (UTC
 * Should the (disused) Twickenham Foot Tunnel (west of Richmond, between Twickenham road bridge and Richmond Railway bridge) also be included here? The buildings at each end are in good condition, and there are printed sources out there that report the tunnel is still there, albeit very little online - but I know little else about it.  Somewhat further upstream than the others cited here, but arguably still 'London'.Curran2 (talk) 17:18, 29 March 2009 (UTC)


 * That wasn't a foot tunnel by Twickenham bridge. It was built by the Metropolitan Water Board to house water mains.
 * Going by https://ravenwing93.co.uk/2013/01/metropolitan-water-board-company-mains-tunnel-richmond-january-2013, that would be a very cramped tunnel to walk through.
 * There's a bigger one between Willoughby Rd and the back of the White Cross, also for water pipes. Looks like the west side is in the middle os someone's lawn. https://www.google.com/maps/@51.4574276,-0.3087396,136m/data=!3m1!1e3?entry=ttu

Original research.
The last sentence of the last paragraph reads like original research and appears to contain an opinion. The decline of the Port of London as a trading port has opened up the possibility of further bridges to be built east of Tower Bridge, as very high clearances i.e. over about 150 ft (50 m) are no longer required upstream of Dartford.

Update and image removal
I've updated the article to reflect the fact that High Speed 1 and the Docklands Light Railway extension to Woolwich Arsenal are now open, and these tunnels have been added to the list. However, I wasn't able to update the map (File:Thames tunnels.svg): this has been commented out until it's been fixed.

I've also updated the bit about Crossrail, since the go-ahead has now been given to this (and work has started). --RFBailey (talk) 16:06, 21 September 2009 (UTC)

Background section, how many bridges?
"Only three railway bridges exist in central London", I assume those are the *four* into Cannon Street, Blackfriars, Charing Cross, and Victoria? Or isn't Victoria central enough? There are also many other railway bridges to the west of Victoria. TacoJim (talk) 13:12, 30 September 2010 (UTC)

Article is out of date
The article is becoming increasingly out of date and there are a few omissions. But how the hell are you supposed to edit this complete hotch potch of an article? 86.131.235.171 (talk) 18:28, 10 July 2022 (UTC)


 * Which tunnel do you want to add? I can help ... &mdash; Martin (MSGJ · talk) 19:19, 10 July 2022 (UTC)


 * The one that needs to be added is the cable tunnel that carried the pair of +/-266 kV DC cables from Kingsnorth power station to Beddington, plus its companion that carried the negative pole across to Willesden. Although the DC link is no longer extant, the tunnels must still exist. I am trying to find some more details about these.


 * The Rotherhithe tunnel is shown as being a road and pedestrian tunnel, but the pedestrian part has not been the case since the 1970's. But why is this article uneditable? 86.131.235.171 (talk) 13:50, 11 July 2022 (UTC)
 * The data is stored on Wikidata and is editable if you press the pencil icon in the first column! Once you have some more details (dates, location, references, ...) I can help you with the new entry &mdash; Martin (MSGJ · talk) 14:01, 11 July 2022 (UTC)
 * No pencil icon in first column. There is one at top of edit screen, but all it does is turn the table purple. There is still nothing to edit. 86.131.235.171 (talk) 17:17, 11 July 2022 (UTC)
 * Sorry I think the pencil only shows for logged in users, that probably explains it! This was to reduce clutter for readers who will usually be unregistered. If you could log in, you will see all those pencil icons which link to the corresponding Wikidata items. &mdash; Martin (MSGJ · talk) 07:29, 12 July 2022 (UTC)
 * The Rotherhithe tunnel is still useable for pedestrians, you just can't use the intermediate stairs. That's different from the Blackwall tunnel where pedestrians are banned. Davidwalters (talk) 14:14, 11 July 2022 (UTC)
