"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. " 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. 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. Cheers Dave F. Look at this example and ask yourself how to tag track=* on each way according to that user's concept ;-) 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. Now if you look at this ... isn't it tempting to map each rail? :-)  One even sees where their straight line segments meet. But, last question, what's the use of mapping such "micro" details if the renderers do not show them. I have mapped cellphone aerials (man_made=tower, tower:type=communication), several on water towers like this. The water tower or other support shows, but never the aerial. Best regards, André.
