AI Trains

[sidc121]

Hi,

I am playing MSTS using open rails. The game works absolutely fine. However, I have noticed in all activities (almost and this is in case of Indian routes), the AI trains are stuck at a signal and they don't move. In thee activity I see chains of trains standing one behind other (on the opposite direction).

Is it some fault with the signalling system ?

No fault with the signalling system far as I know. It is the lead AI in the queue that is causing the problem, may well be something to do with how the path is made.

I have seen this is a number of routes, especially with areas of intense signaling. I found the solution in response to another issue.

I found that if I needed make a change to the signalNumber look ahead parameter in the sigfig.dat file. Often that number is 3 or 4 I Increased it to 7 and it seemed to solve the problem.

Be sure to make a back-up of the file before you make any changes.

One thing that I noticed on a couple of the "Older" routes, when running OR, if the AI is to start even slightly ahead of it's intended signal, being that the signal would show a red stop, that particular path is now non-existent in the game.

I don't know if that is something that can be looked into easily. Granted that the times this happened was also in an area of high density signals. It must also have to do with the starting point and the starting speed of the AI. I got one such AI restored by changing the "Start Speed" from "0" to "10"mph.

It seems to happen with older routes only, the newer activities also seem to have similar problems when utilizing older routes/paths.

Ummm not particularly the lead AI. But lets assume after three trains (just a fancy number) pass by, the fourth is stuck at a signal (mostly a station siding) and rest trains follow suit. They don't move.

Thanks bprice. I will try that and lets see if it works for this case.

I downloaded a relatively new activity for an old route Don6218.

Which version of Open Rails are you using?, and can you provide a log and a screenshot of the F5 dispatcher window when you find a stuck AI.
