This tool works for the branch geometry that is starting with a tunout. While creating the cant it applies the same cant value it read from main track geometry to the start of the turnout geometry.

Also tool needs to have an option to change rotation point of the cant geometry for the turnout region, to match with the main track. That is if a turnout is placed on left side of a right handed curve (contraflexture turnout), for the main track the pivot is on the right rail. But as the turnout to the left, its pivot will be to the left rail. In this case turnout should fallow the pivot of the main track, that is should change its pivot point from inside rail to right rail, in the turnout region.
