text: I'm guessing that this is referring to https://www.openstreetmap.org/note/831462  , and I'm guessing that you followed a link from https://en.wikipedia.org/wiki/Abbey_Town_railway_station which took you to this spot. The problem (and it's not the only example) is that wikipedia has obtained some inaccurate co-ordinates from somewhere, and is using those to display a marker in OSM.  You'll need to raise it with wikipedia rather than here to get it fixed.  I suspect that the reason why your original note was closed was because you didn't explain the story of how you got there you just said that "something is not here" (which is correct, in OSM it isn't"!
  To discuss further the easiest way is probably via the #osm-gb channel on IRC (see https://wiki.openstreetmap.org/wiki/IRC ) where both the person who closed the original note and the person who commented above are currently around.
