In railway engineering, there is a growing demand for positioning of the tongue in turnouts.

The proposal is to introduce a new point in the Feature Definition of turnouts, making it possible to specify the distance from point .1 to the Tongue. Subsequently, the Tongue point would be incorporated into the property set of the turnout, alongside points Theoretical .1, 1, .2, and .3 so it is possible to annotate this point with an Element Annotation.
