That doesn't make sense. A multilane road is a continuous paved area, while rail tracks are separate, like a dual carriageway road. You can move continuously between lanes of a road (including to the other side if you U-turn), but trains can only switch tracks at crossovers. And yet there are traffic rules, so mapping the street as an area is probably not the correct solution. _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
