For some reason, I am running trains on the NCL of pagroove's Electro Island and I'm getting a "cannot find destination" message when there is literally no faults in the track and the destination is on the track. Is there a way to fix this?
Place track marks along the path your AI driver is supposed to drive at various locations.
Get in the cab with the AI driver and go for a ride with the AI driver and have the AI driver drive to each track mark. You may want to do this one at a time rather than put them all in the schedule.
The AI driver will drive until it reaches a point where it can't and post the message "Can't plot route to selected destination" and halt.
At this point, you take over driving.
Get out of the cab and continuously check the track for broken spline points. Here the track will appear lifted or separated.
If nothing is found, you will need to inspect the route in question in Surveyor. This means following the track above while looking for issues such as broken track splines, disconnected level crossings, and direction markers facing the wrong way.
In the end, if nothing is found, then it may be a schedule issue. Check your schedule carefully as you may have put in an incorrect destination such as the wrong platform that's blocked by a disconnected track or direction marker.
This process can take time, so plan on spending it with a lot of patience.
