Talk:Level junction

In the UK we often just tend to talk about a crossing, where railway lines cross each other.

However, for us, where a roadway crosses the line we use the term "level crossing". Is it the same in other countries?

 * In the USA, a roadway and railway crossing is called a grade crossing, meaning they are at the same grade, not over or under.Keo 19:10, 17 July 2006 (UTC)

Double junction
The diagram in the Level junction article is of a Double junction. Biscuittin (talk) 20:25, 28 March 2009 (UTC)
 * Flat vs. grade-separated (or as the LEAD notes, a flying junction). It's not incorrect, but if you can suggest ways of improvement I can probably tweak another variation on the diagram.  —Sladen (talk) 20:41, 28 March 2009 (UTC)
 * Thanks for your reply. I think there is some confusion about terminology.  What is the definition of a level junction? Is it identical to a diamond crossing, or is it any junction (including a double junction) which incorporates a diamond crossing?  I think this needs to be clarified.

 * Sorry, it is explained in the article but I have modified the text to make it clearer. Biscuittin (talk) 10:12, 29 March 2009 (UTC)

What's going on, Ted?
The article is titled "Level junction" but, aside from the first and third paragraphs of the intro, the article discusses exclusively flat crossings, i.e., two lines crossing without a junction. That's a completely different subject. In particular, it's impossible to have a level junction, or any other sort of junction, between two lines of different gauge. They can cross each other (flat crossing) but they can't join (level junction).

Also, the assertion that diamond crossings are dangerous because the flanges are unguided seems dubious to me. In normal operation, the flange is not in contact with the rail &mdash; the flange only comes into play around tight corners, and you can tell when it's in contact with the rail because of the loud scream of metal grating against metal.

 * Yes, this article could perhaps be split to cover flat crossings. Level junctions can exist on dual-gauge systems (two gauges, one right-of-way).  And flanges are generally supported across non-moving frogs.  —Sladen (talk) 10:33, 8 August 2009 (UTC)

Subject?
This article is confusing.

I got here from a link to level junctions (as opposed to flying junctions), and the first picture (with green and yellow track) supports this.

But then the text focuses on crossings without junctions? That's another article altogether. CapnZapp (talk) 08:09, 11 November 2009 (UTC)

File:CTA loop junction.jpg to appear as POTD soon
Hello! This is a note to let the editors of this article know that File:CTA loop junction.jpg will be appearing as picture of the day on April 15, 2012.
