Facing turnouts/points

When you have turnouts/points that face each other, its awkward for the throttle user to have to manually switch both to match each other. By treating the crossover as a single turnout, control is simplified and incorrect combinations are prevented.

To do this, we need to hide one of the turnouts/points from the user, and make sure that throwing/closing the visible turnout automatically throws/closes the other turnout.

All turnout/point definitions in EXRAIL allow for a text description to be shown to the user throttle. The HIDDEN keyword, used instead of a turnout description prevents it being visible to the throttle or JMRI/iTrain etc.
