I have resorted to changing railway=abandoned to railway=disused on several occasions just to get mapnik and friends to render bridges. Bridges over roads and rivers are major features of relevance to tall vehicles and boats, so really should show up on standard rendering.
According to the wiki railway=abandoned applies when the rails have been removed, and disused should be used when the rails are still present. Not suprisingly this has been raised before, as for instance at http://wiki.openstreetmap.org/wiki/Talk:Railways. I don't like tagging for the renderer and normally avoid it, but in this case it seems to be necessary to maintain the reputation of OSM/mapnik. A quick search of the wiki didn't find where to report bugs on the standard mapnik osm style, but I can't imagine that this has not been raised before. Should I just switch to "disused" even when no rails are present? ael _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
