I found a section in Brooklyn where the elevated railway has duplicate nodes where it passes over streets. I use JOSM and I think one node is for the street and another for the railway. I have two questions
1) I don't think i should join these nodes, i think both should be deleted so the street and the elevated train are not connected or intersected, is that correct? 2) how can I tell in JOSM that a node is part of a particular way, when I click on the dupes I cannot tell if it belongs to one or both ways. http://www.openstreetmap.org/?lat=40.6794&lon=-73.95549&zoom=17&layers=B000FTF I did find your changes in potlatch easy to use and it will help greatly to cleanup these dups.
