I too think that tracks should just be a single lane. From the reasons stated above put more by Kytömaa Lauri more eloquently than I will. If a road has a physical split it is 2 separate one way streets. Tracks are physically separate so they should be mapped as such.
Roads and the crossings of multiple tracks are a little tricky but maybe this can be done as a relation rather than a node. I am no expert on tagging railway crossings. As San Fran doesn't look like it has many railways I suggest you look at locations around the world maybe UK that has a detailed rail infrastructure so you get a better understanding about how it is done there. Most of your issues seem to be about the rendering of the map rather than the map data. -- View this message in context: http://gis.19327.n5.nabble.com/Feature-Proposal-RFC-More-Consistency-in-Railway-Tagging-tp5756879p5756913.html Sent from the Tagging mailing list archive at Nabble.com. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
