[edit] Length

The article has the tunnel length as 2.4 miles; Jim Shead (see external links) has it at 2.9. Which is correct? Andy Mabbett 10:39, 16 April 2007 (UTC)

If your coordinates had been left in place, checking the length would have been a simple calculation. Martin Cordon 14:56, 17 April 2007 (UTC)

If the coordinates are correct the tunnel is 1.74 miles long and the total canal length is 2.4 miles. Martin Cordon 21:46, 17 April 2007 (UTC)
Thank you. What's the formula/ method for that, please? Andy Mabbett 22:47, 17 April 2007 (UTC)
Distance = Radius of Earth*Pi*cos-1(cos(Latitude Point 1)*cos(Latitude Point 2)*cos((Longitude Point 2)-(Longitude Point 1))+sin(Latitude Point 1)*sin(Latitude Point 2))/180 Use decimal latitude and longitude. cos-1 is supposed to indicate inverse cosine, Radius of Earth about 3960 miles or 6373 km according to Wikipedia. Multiplying by Pi and dividing by 180 converts the interim result in degrees into a result in radians. Martin Cordon 23:58, 17 April 2007 (UTC)
It is onle now that I find that there is a Great-circle distance article which describes this formula. Martin Cordon 00:11, 18 April 2007 (UTC)
Thank you. I used to enjoy maths, a long time ago. Now I can't remember why..! Disappointingly, none of the external links on the above page is to a site which lets users enter two sets of coordinates, then returns the distance beteeen them. Do you know of such a site, or a freeware Windows utility, which does that (I'll ask there, too)? Andy Mabbett 11:42, 18 April 2007 (UTC)
Yes. If you import the coordinates into GoogleEarth there is a Measure facility in the Tools dropdown menu. Martin Cordon 14:11, 18 April 2007 (UTC)

[edit] Tinsley Viaduct

A Concensus reached with respect to an issue discussed on the Tinsley Viaduct article cannot be taken to apply to all pages on Wikipedia. If there is an objection to the inclusion of information on the Netherton Tunnel Branch Canal page discuss it here. Netherton Tunnel Branch Canal is significantly longer, bigger and more substantial than Tinsley Viaduct. Like is not being compared with like. Martin Cordon 14:54, 17 April 2007 (UTC)

Quite. See also Digbeth Branch Canal and Manchester Ship Canal. Andy Mabbett 15:04, 17 April 2007 (UTC)

[edit] Co-ordinate list vs route table

These two contain much the same information. Can they be combined? --VinceBowdren 18:34, 17 April 2007 (UTC)

  • This subject is under discussion at the UK Waterways WikiProject. Martin Cordon 20:05, 17 April 2007 (UTC)

[edit] Old Steam Engine Building

There is an old building near the South Portal of Netherton Tunnel which looks like an old engine house. Does anyone know what it is? It may be worth including this information in this article. Martin Cordon 00:03, 18 April 2007 (UTC)

Is this the Cobbs engine house mentioned in the article? Martin Cordon 00:24, 18 April 2007 (UTC)
Yes. Andy Mabbett 11:32, 18 April 2007 (UTC)
