Hi,
first I apologize for starting this thread in case the described problem was already discussed in another. But I searched this forum using problem related keywords and I either get many irrelevant matches or no matches, but nothing that could solve my problem.
The problem I have is that in some situation (about 30% of time) AI driver is unable to complete the command "Run Around". This is the built-in command, <kuid:-3:10083>. This problem occurs in TC version 3.17, build 3233.
As I understand, this command should be performed using the following steps:
1/ Decouple loco from the first vehicle in the consist
2/ Drive forward to a point A
3/ Drive backward to a point B
4/ Coupe loco to the last vehicle in the consist
What happens is that AI driver performs steps 1,2,3 correctly, but fails to complete the last step - it drives back to point A, passing the consist on a nearby track. Then it drives back to point B and continues circulating between points A and B forever, like a pendulum. If track at points A and B was not terminated by a signal, then AI driver would likely to drive off the track and derail.
This problem occurs in some situations only, but I can't really find out what condition causes it. On some yards this command works, on others it doesn't and it is very difficult to tell why.
Very recently I modified track layout in one of my routes. I had a yard with 6 additional tracks, on which AI driver performed "Run around train" command without a problem 100% of time. Then I removed 3 tracks and slightly re-arranged turnouts at the yard ends. After this change AI driver has problem completing this command each time.
I tried to isolate this problem and created a test session, without any additional rolling stock. The command "Run Around" fails each time, despite there were no commands executed prior to this command. This makes me believe that the problem is with the track layout or signalling. But what exactly? If I knew, maybe I could find a way to fix it.
Of course I could substitute "Run Around" by the following commands:
1/ Decouple from vehicle 1
2/ Drive To Trackmark A
3/ Drive To Trackmark B
4/ Couple to vehicle n
But this is complicated and error prone. I could mistakenly select wrong vehicle. Say instead of TRS Tanker 46 I could choose TRS Flatcar 46 and after few minutes discovered the loco miles away from the place it should be. "Run Around" is a very convenient command. But why it does not work?
I would much appreciate any feedback in this matter.
