Deletion of Mountain railways special exhibition in the Hünegg Castel

Comment: WP:N|Notability isn't conferred by the impressiveness of the exhibition, but by '''signficant coverage''' in '''|reliable sources'''.  The brochure of the exhibition, or its website, or the website of the castle (which, by the way, appears to fail to mention the exhibition at all) do not count as reliable, independent sources.  Find some actual sources, and the story here might change.  As for my comment about "PROD removed by a single purpose account", that refers to the fact that new users who register solely for the purpose of commenting on deletion processes generally raise red flags, due to their unfamiliarity with Wikipedia policies and guidelines, and to the possibility that such accounts are |created maliciously to subvert the deletion process.  That is not the only reason such accounts are created, but it does become a factor in the deletion decision process
