Switch puzzle

[NW Mailing List]

It doesn't look standard gauge to me; maybe for a mine or logging operation?

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?
