<p>Thanks for contacting DWG, Michael.</p>
<p>It is not limited to tracks=2 by the way - I have seen examples of four tracks, all with tracks=4...</p>

It may need something like<br /> this: <br /><br /> * Get all changesets from WJtW<br /> * get all railway tracks from those changesets with tracks>1<br /> * search back through the history to find where the tag was added<br /> * see if it was user WJtW that did it<br /> * If so, remove the tracks=* tag.</blockquote>
<br /> I (a German railway mapper) have been notified by another user about<br /> WJtW's edits last week. I [1] have already started reverting parts of<br /> his edits. That's the way I did it:<br /><br /> - Search for railway=rail + tracks=2 via Overpass Turbo (with meta as<br /> output variant)<br /> - Pick out one way of the result. If its last edited was done by WJtW, I<br /> had a lookat the changeset which did this edit using Achavi. If the<br /> changeset was mostly adding of tracks=2, I reverted it. Sometimes I did<br /> partial reverts if only parts of the changeset were bad.<br /> - If the last edit of the way was done by another user, I had a look<br /> into the way's history and looked for the bad changeset(s) there.<br /><br /> You have to repeat this until the area which you are going to clean is<br /> free of tracks=2.<br /><br /> Note: If you are looking at the area between Dortmund and Cologne –<br /> there are lots of ways with tracks=2 from old times (about 4 to 7 years<br /> ago) because tracks=2 has not been removed when the second track was<br /> added to OSM.<br /><br />

<br /> I have asked DWG to block him (0-hour-block) because he has been<br /> notified about his errors several times:<br /><br /><a href="https://www.openstreetmap.org/changeset/34049497">https://www.openstreetmap.org/changeset/34049497</a> (21 days ago in German)<br /><a href="https://www.openstreetmap.org/changeset/34264606">https://www.openstreetmap.org/changeset/34264606</a> (11 days ago in English)<br /><a href="http://www.openstreetmap.org/changeset/34313237">http://www.openstreetmap.org/changeset/34313237</a> (7 days ago in English)<br /><br /> It is not the first time that a user used tracks=2 the wrong way. There<br /> were/are users from time to time who add tracks=2 because there was a<br /> map by ITO rendering tracks=2. I asked the people from ITO to shut down<br /> this map a few days ago to prevent future abuse of tracks=2 as tagging<br /> for the renderer. I thank ITO for their quick reaction (the took the map<br /> offline). <a href="http://www.itoworld.com/map/group/1">http://www.itoworld.com/map/group/1</a><br /><br /> Best regards<br /><br /> Michael aka Nakaner<br /><br /><br /> [1] via my cleanup account Nakaner-repair<br /><br /></div>
