There must be an easier way of finding a junction with a missing lever than having to trace the whole route to find the offending junction. Anyone know of a method? Thanks Keith.
TS12 unable to plot route junction is missing a lever
- Thread starter railsignal
- Start date
When I get that report from an AI train what I do is place temporary track markers between the point where the AI stopped and the destination he can't find a way to get to. Then create a temp session with instructions to navigate to mark 1, mark 2, and so on. If he stops at mark 5 and transmits that message, I know the problem is somewhere between 5 and 6, so the next step is move 1 to where 5 is, then 2 3 4 and 5 between that and 6, repeat the session until I narrow down the actual location.

OK thanks guys, looks like it's going to be a long night.
Actually, you don't need to place so many at once. Put one about half way to the destination. If the AI can reach it, the problem is on the far side of that point. if not, it is on this side of that point. In either case, move the track mark half way in the suspect area and repeat. Even the longest routes will very quickly reduce to one of a few possible junctions that are missing a lever.

No! It is one of my own routes a one I have been working on for the past four years and as you can imagine it is now rather large. From Edinburgh and Glasgow in the North down to Carlisle and Newcastle, down to Skipton and Leeds and across to York. Using the pre 1950's routes and branch lines. Quite a lot of track, sidings and over 4,000 junctions or points as I prefer to call them. I started last night as was suggested with track indicators and guess what the train went staight there not a problem. So therefor the train that is causing the problem must be using a different route than the main line. I have back tracked recent changes all to no avail but I will eventually find the offending set of points. Thanks for your help and suggestions guys i'll keep trying. All the best. Keith.
AI's will always go for the short route (take the inside of a long bend for eg). Or go through an industry with a 5 mph limit instead of the main with a 50 mph because it's shorter.
I've tried tempting my lot with higher speeds on the logical (to me) route but they go there own merry way and only use my way if the other tracks are in use.
The bankers come out when they stall so it keeps me busy.

Hi Fran. You could use track markers to direct your trains in the desired direction using track markers and then tell your train to navigate via trackmark (???). All the best. Keith
Usually do, apart from 1 route with 4 bi-directional lines and loads of x overs. It's like wacky races with my 6 morons.
There is nothing wacky or moronic about the AI behavior. They are doing exactly what they have be told to do, find and use the shortest possible route between two points. If that takes them through areas the route designer doesn't want, then it is up to the route designer to arrange things so those possibilities are not available. The AI can not read your mind. You may call a section of track a mainline and another a secondary line but to the AI, both tracks look the same. By using the track markers and the direction markers, the designer can influence the logic to get the desired results. Given proper guidance, I have found them to be pretty clever in sorting out conflicts and finding their way to their destinations.

My question after reading is what is the difference between drive to and navigate to?
The difference between 'drive to' and 'navigate to' is explained in this blog: http://forums.auran.com/trainz/entry.php?951-Using-the-Trainz-AI-in-sessions-Part-1
