Derailment Due To An AI Collision

[DESPATCH]

I have been running the Spring Local to Evercreech when the above notice came up giving the name of the consist and a latitude and longitude. Where do I go from here as I'm not sure where to find it to correct the problem?

Hi,
As no one else has replied to you, my advice would be simply to run the scenario again and see if the same thing happens each time.
The Despatcher does recalculate all of the AI paths again from scratch each time you play, and it can come up with some 'funnies'. I have had that sort of thing happen as a 'one off', and then the scenario has worked perfectly every other time. I have also met an AI train head on on the same track - Crash Bang Wallop! But that has only ever happened to me once, a long time ago.
If it was one of my own created scenarios, and the same thing happened again, I would simply start one of the AI trains at a slightly different time, and that would probably cure the problem. I have never altered any of the default scenarios myself so I don't know if you allowed to do that or not.
regards Ted.

I had this problem a while back and fixed it by deleting one of the offending consists using RS Tools.

Something else you can do to find it, is use the 2d map ( keeping a eye on the AI trains running ) to see where and what is happening. If you are able to note the co-ordinates down and service name its possible to check them via the editor so you know where to look. If you know when it happens in the scenario save before it gets there so you don't have to run the whole thing again to find the info

Hi

You can get this message when there are other problems such as breaks in the track. You also need to check if you have been derailed due to trying to cross points that are set against you. This does sometimes give an error message about AI traffic when in fact none were involved.

Thanks for the helpful advice. The notice has told me the position and the consist involved but I am not yet conversant enough to get there. I will run the scenario again to see if it a one off or I may remove the consist using RS tools. Perhaps when I have mastered navigation I will do more.

Hi guys

I do not know if this issue has been resolved, but I have the same problem when running this scenario, and the same thing happens every time I approach Shepton Mallet. Changing to the 2d view, I can see what happens and where: The 'Heavy coal' service derails right at the spot where the 'Shepton Mallet Shunt' waits for a red signal. I first thought that this consent overran the signal but when I zoomed in it appears not to obstruct the mainline. The heavy coal however derails right here, when it passes over a point. When it happens you can see at least 2 wagons derailling. The message shows the position as : Long. 2'53282 / Lat. 51'18342.

As I am new to RS I have no clue how to correct this. I have looked in the RS Tools Pro utility but again have no idea what to do. The only possibility here seems to delete the heavy coal consist, if allowed at all, I did not try it.

Does anybody here have an idea how to correct this?

Hi

Are you absolutely sure that the blue line path extends right across the points in the direction you want to go?

Hi Geoff,

It's not me, or better my train the Spring Local. The derailment happens with the AI train/consist called "Heavy Coal' a few miles down the line, in the opposite direction; so on the other line heading North. My train is doing fine, only the sim stops because of the AI train derailment, so I can not finish it!

Hi

I will try and look at this a bit more closely. I am sure you have checked a lot of possible causes but are there any physical gaps in the track?. Again the 2D map should show gaps but take a close look with the camera and see if the track itself has been broken or out of alignment.

Another remote possibility is that there is something in the way but it is not showing. Have you checked that all stock and assets are included in the route. You will need to use 'Tools' to check for missing route stock and scenario stock.

These are just suggestions which may help but as you seem to have checked the situation out yourself quite well already, perhaps not.

Hi As the scenario creator, this is the first instance I've heard of this and I'm not at a PC where I can check it - and I won't until the weekend. I'm snowed under in work right now, I'll try to think it through later on.

Hi Geoff

I have not checked with the camera. Not enough time as the AI collision happens just e few minutes after my last save and that stops the sim.

I have checked all stock and assets using RS Tools, all OK.

Thanks for your suggestions.

Hi Paul

No hurry, I know the feeling and I too won't be at my PC and run trains in RS anyway during the week. So take it easy. Disregard the PM that I sent you; it is about the same issue.

Let me know when you need more info.
