"No Path To Selected Destination"

[Glenethson]

When I tell a train to travel from one station to another I get the "No path to selected destination" error. But if I driver the train slightly closer and then press "Continue schedule" the train will drive to next station like nothings happened. This same thing also happens except with junction levers. It tells me one is missing but there isn't a missing one.

I am using TS2009 SP1

Any Theories?

Hi Glen, Double check your point levers.
I have sworn I had them all placed only to find one missing after triple checking! And remember - they must be just inside the spline circle for an AI to recognize them. If they are centered in the spline circle or too close to the junction end of the spline circle there is a good chance that the AI loco wont see them. Slide the red/green arrow back past the center of the circle.
Also make sure that the track is properly connected at the spline points. Sometimes the track comes together but is not fully connected. This is rare but I have experienced it a few times.
Best thing to do is move the loco closer to its destination until it obeys your command. Then check the spline points and junctions in the area immediately behind the loco.
It can be a bit of a laborious process but there isn't an easier way that I'm aware of.

Good Luck!

You will get the "No Path" message when the AI can't find a way to the specified destination. This usually indicates a break in the track, missing or non functioning lever or similar problem.

You problem will lie somewhere between the first location at which the command wont work and the location from which it will work.

Sometimes levers can appear to be in place OK but are not quite right and will not work for the AI. Just remake the junction(s).

Worth a check also to see if you have track direction markers confusing the AI, although I'm not sure if they would give the "No Path" message.

no path

Glenethson To check to see if your switch levers are in the right place is to open track fly out place your compass over the switch spline then click on track spline in the fly out. your green & red arrows should be in the center of your compass,if not move them there.

Here's another to check.I made asmall (6grid) layout) for fun. Just a circular double line, then put a consist on each line and gave TM commands. They wouldn,t follow orders. Guess what, I had put a track spline exactly on the joined grids and the track had different heights. The track would not join properly until I moved the spline circle a little. Strange.

I have to disagree with Danny5. (Sorry Danny)
If you put your switch lever exactly in the center of the switch spline circle you will have a problem with AIs finding their way. (Unfortunately, this is where Trainz puts them).

You need to pull the lever back from the centre, away from the junction. Just enough to get it in the middle of the half circle.

I generally place my levers completely outside the spline circles to avoid the problem. You can slide the lever away from the junction until both arrows turn red(then you are too far away). Then move closer to the junction until one arrow is green and the other red and you should have no problem with AI operation.

BTW I run TRS2004.

BTW nawlins where do you live? I lived on Jefferson Ave Uptown until Katrina and then I moved to Hattiesburg.

Just a thought

This is just a thought and worth a check, I know because I have done it myself.

When laying track it is possible to accidentally add a short extra bit under the existing track. You can't see it and that will often produce this message.
Look out for a completely red point direction indicator (no green side) or check by moving track splines sideways that there is not that odd bit underneath.
You can cut down the amount by using the suggestion above of running short distances. Put red track markers in for a distance that includes a couple of track splines and then run to it. Eventually you will find the section with the fault.

Hope that helps.

I don't know if this has already been suggested, but sometimes if you have altered the track in any way, the switches, and signals for that mater, tend to shoot half way down the track, and if you've replaced them with new ones, you must make sure that you have removed all the disrupted ones, as one rouge switch can cores your problem.

This is correct and it is so easy to miss a wandering rogue switch (point) lever that has slid along. You see a switch witout a lever and stick on in but the spare will stop your train.
So another check for you to do and do these examinations carefully because it is very simple to miss the problem.

Hi Earl, I live in Kenner, Chateau Estates. Hope you're enjoying Hattiesburg. You should be safe from Hurricanes up there!.

OK, back to the thread. One more thing to check is the direction markers. If you have a yellow direction marker facing the wrong way, the AI cannot proceed.
