<font face="Arial">Hi<br>
<br>
A user in GB has been editing railway lines by adding tracks=4
even though each individual track has been mapped:<br>
<br>
<a moz-do-not-send="true" class="moz-txt-link-abbreviated"
href="http://www.openstreetmap.org/browse/way/174899570">www.openstreetmap.org/browse/way/174899570</a><br>
<br>
From the railway page of the wiki:<br>
<br>
"When modeling multi-track parallel railway lines in close
proximity they can either be modeled as a single way with
tracks=*, or as a number of parallel ways."<br>
"The tracks=* tag should be used to record the number of tracks
with a default value of 1 being assumed where this is not
supplied. "<br>
<br>
In the example he's tagged each way with tracks=4. Going on what
the wiki says this implies there are a total of 16 tracks on the
ground. This seems incorrect tagging to me.<br>
<br>
I've contacted him directly & received a reply but he
appears to think his way is correct & the wiki wrong, so I'm
posting here for advice & clarification.<br>
<br>
Cheers<br>

at this example</a> and ask yourself how to tag track=* on each
way according to that user's concept ;-)<br>
<br>
I have found interesting to map two tracks (vs one line) to visually
stress that a single track line splits in two on some distance
(where trains cross like when the English drivers hand those
anti-crash control sticks over). My question is: how do I include
the second track in the relations containing the single line? Same
question when the line is two tracks fully, of course.<br>

Now if you look at this</a> ... isn't it tempting to map each
rail? :-) One even sees where their straight line segments meet.<br>
<br>
But, last question, what's the use of mapping such "micro" details
if the renderers do not show them.<br>
I have mapped cellphone aerials (man_made=tower,
tower:type=communication), <a
href="http://www.openstreetmap.org/?lat=50.534604&lon=5.626856&zoom=18&layers=M">several
on water towers like this</a>.<br>
The water tower or other support shows, but never the aerial.<br>
