<p>I am not sure it would be vandalism - It is more likely a misunderstanding of the intention of the tracks=* tag. But it is very damaging, and potentially hard to revert as this has been going on for some time and newer edits may have been made. It may need something like this:</p>
<ul>
<li><span style="font-size: 10pt;">Get all changesets from WJtW</span></li>
<li><span style="font-size: 10pt;">get all railway tracks from those changesets with tracks>1</span></li>
<li><span style="font-size: 10pt;">search back through the history to find where the tag was added</span></li>
<li><span style="font-size: 10pt;">see if it was user WJtW that did it</span></li>
<li><span style="font-size: 10pt;">If so, remove the tracks=* tag.</span></li>
</ul>
<p>But in Dutch (as you will know) there is a wonderful expression about trying to mop up (a flooded bathroom) while the tap is still running. We need to turn the tap off and stop this getting any worse.</p>
<p>It's starting to sound like a candidate for a user block until the user engages in some kind of dialog.</p>

Most of them are adding tags like gauge=1435 which may</span><br /><span style="white-space: nowrap;">well be right (although I have no idea of his source for this).</span><br /><span style="white-space: nowrap;">However on many occasions he has added tracks=N to the individual</span><br /><span style="white-space: nowrap;">tracks where they are already mapped as N separate tracks. According</span><br /><span style="white-space: nowrap;">to the wiki this should now be interpreted as N*N tracks. For example,</span><br /><span style="white-space: nowrap;">the Channel Tunnel Rail Link south-east of London, is composed of two</span><br /><span style="white-space: nowrap;">tracks (see [<a href="http://www.openstreetmap.org/way/34574683">2</a>] for a sample way). They are now both tagged with</span><br /><span style="white-space: nowrap;">tracks=2, saying that each way represents 2 tracks, suggesting there</span><br /><span style="white-space: nowrap;">are 4 in total, which is wrong.</span><br /><br /><span style="white-space: nowrap;">I have sent two messages explaining as above and requesting that they</span><br /><span style="white-space: nowrap;">review this tagging, but no response so far. I noticed that another</span><br /><span style="white-space: nowrap;">mapper has also added a comment to at least one changeset with the</span><br /><span style="white-space: nowrap;">same intent.</span><br /><br /><span style="white-space: nowrap;">Any ideas how we can stop this behaviour, and repair the "damage"?</span><br /><br /><span style="white-space: nowrap;">//colin</span><br /><br /><span style="white-space: nowrap;">[1] <a href="http://www.openstreetmap.org/user/WJtW">http://www.openstreetmap.org/user/WJtW</a></span><br /><br /><span style="white-space: nowrap;">[2] <a href="http://www.openstreetmap.org/way/34574683">http://www.openstreetmap.org/way/34574683</a></span><br /> _______________________________________________<br /><span style="white-space: nowrap;">talk mailing list</span><br /><span style="white-space: nowrap;"><a href="mailto:talk@openstreetmap.org">talk@openstreetmap.org</a></span><br /><span style="white-space: nowrap;"><a href="https://lists.openstreetmap.org/listinfo/talk">https://lists.openstreetmap.org/listinfo/talk</a></span></blockquote>
