Talk:List of spiral tunnels and tunnels on a curved alignment
|WikiProject Trains||(Rated List-class)|
What is a...
It would be useful if the LEAD of this list introduced (in one sentence) exactly what a "turn tunnel" is.
Shouldn't the CPR's rather famous Spiral Tunnels in the Big Hill article be on this list? There may also be other applicable tunnels on this page, Spiral (railway), that should be cross referenced. The reason I'm not doing it is that I am not a rail and/or tunnel aficionado and don't feel completely qualified. WCVanHorne (talk) 16:24, 27 May 2009 (UTC)
Name of the page
The topic of this page is not to show deployments of curved railway lines including some tunnels but presenting loops and spirals IN tunnels.
Therefore I suggest to relocate this page back to "Table of Turn Tunnels (Railways))". There are so many loops and spirals in the world that the topic of the the page will be weakened.
I could help with to collect open loops around the world since I'm planning already to make a list for Switzerland.
Put your comments to my discussion page. Lord Koxinga (talk) 18:44, 29 May 2009 (UTC)
China seems to have an increasing number of spiral tunnels. eg on the Liupanshui–Baiguo Railway http://highestbridges.com/wiki/images/4/43/BeipnRailwayDescent.jpg --Firefishy (talk) 17:34, 28 May 2013 (UTC)
