dricketts, upload bot kicked back some of my uploads for no thumbnail when they actually have a thumbnail, so it still has a few loose screws, but the invisible permissive made it through so try that and see if it works for you.
Irving, "Navigate implies taking a non-blocked path and routing around blocking trains" more to it than that, see the video;

The AI train chose that weird path despite being the only train on the route and having clear signals on any route. Possibly the logic is fastest speed or least number of signals - I originally thought number of switches involved on the path might be a factor, but note in the video the AI chooses the path through a yard ladder with a lot more switches than the direct route. Maybe it's something bizarre like flipping switches at random and picking the first combination that gets him there. Funny how drive works so much better than navigate, yet navigate is activated by default and drive is deactivated by default, you gotta check the drive commands on in the rules before you even know they exist.
