I've had problems in the past with a reverse loop not switching the junction for the loop exit path. I fiddled around with it and it finally worked. It was months ago, so I don't remember what I did.
So, I set up a test on a new empty baseboard. I carefully laid track from the left and into a counter-clockwise direction and formed a junction. I placed TM's, a buffer and a loco. I assigned the AI Driver: Drive Via TM LoopEntry; Drive Via TM Loop Exit; Drive To TM Loop End.
QuickDrive. The loco incorrectly went to the clock-wise direction (up). I tried it with the beginning orientation of the junction to the right (down in the pic). No difference.
I placed a MU on the track and a dummy building to show where it was.
I removed the Drive Via TM Loop Entry and replaced it with Navigate to MU.
QuickDrive.
The junction immediately switched to the lower path. The loco went to the MU and continued counter-clockwise to TM Loop Exit. The AI set the junction to allow the loco to exit and go to TM LoopEnd.
OK Maybe a fluke.
I repeated the TM only process from scratch.
The only difference was this time,after setting the Driver Commands, I exited Trainz completely. Went back into Trainz, Drive Session. The loco took the wrong path.
Quick Drive from Edit Session and Drive Session from the Menus both took the same wrong path.
I tried DriveTO TM Loop Entry. Loco still goes the wrong way.
I added a WaitFor 20 Seconds as the first command. Loco still goes the wrong way.
I again added a MU and replaced DriveTo LoopEntry with Navigate to MU.
It worked.
Now it gets weirder. I went back into Driver Commands. I deleted the NavigateTO MU. I added back the DriveVia TM LoopEntry.
It worked! Just the presence of the MultiIndustry New changed (in this case -
corrected) the behavior of the AI.
It works regardless of the starting orientation of the junction.
GreyMaster,
Try sticking a MultiIndustry New in your loop where I did in the pics. You don't even have to configure it to Produce/Consume anything. You don't even have to drive to it.
Let me know if it works for you.
This should be easy for N3V to duplicate and, hopefully, fix.
