PS - I have refreshed this page twice since posting my comment immediately above.  Each time it has displayed about five anti-rail comments first, followed by four conventional pro-rail comments (which previously were first when I wrote my comment above), and then everything else in what appears to be more or less random order--with one noticeable (to me) exception.  It seems that most of what I consider to be the most novel and forward-thinking comments (and not just my own:) have been relegated to the bottom.  So, again, I would like to better understand how your ranking system works.  Mahalo:)
