Switch puzzle

[NW Mailing List]

On second thought, this could be a switch used for light rail (street car) systems to allow cars to pass on single track routes.

  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?
