You can build rails through gates, but only if they are perpendicular to the gate - but it won't work for diagonal tracks. Not sure if this is a bug in the implementation, or in the wiki (need to call out it doesn't work diagonally) - since it says that rails can go through gates - and I would expect the lower rails would go through those gates.

This behavior is unchanged from 0.16.

You haven't been able to do this since at least 0.16. I don't think it's a bug.

Not a bug, just desirable behavior. Put it in suggestions. Diagonal gates.

Thanks! Will do.
