Hi
A user in GB has been editing railway lines by adding tracks=4 even though each individual track has been mapped:
www.openstreetmap.org/browse/way/174899570
From the railway page of the wiki:
"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."
"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.
The wiki is correct. This is similar to the way roads are mapped - when a road that has lanes=2 is split into two parallel one-way roads, they are each tagged lanes=1 to continue to correctly indicate the number of lanes that each way represents.
Similarly, if you were to split a railway with tracks=2 into two separate parallel tracks, each would be tagged tracks=1 (or have no tracks=* tag at all, since this is documented to mean the same thing as tracks=1).
