Problem is lines are sold between companies. Perhaps the best is old_operator:1945 or some other single year that we use for all lines in a country. This is essentially what I did with old_railway_operator, but with a little more fudging (a line may not have been operating in 1945, or may have been temporarily leased to another company). _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
