Switch puzzle

[NW Mailing List]

Just a guess, but this may be a switch for a funicular or cable car railway.  Wikipedia explains configurations of these things.  http://en.wikipedia.org/wiki/Funicular    They exist in 2, 3, or 4 rail configurations.  The 2 or 3 rail operations require a switch for cars to pass in the middle of the line.  There are several U tube entires as well.

  This image has appeared repeatedly in a switch manufacturer's ad in various railroad trade journals.  It appears to offer three different routes through it.  Can anyone explain where such a switch would be used?
