interlocking tower path

Hi all
I set a session AI where a train goes to a track mark through several ITs setting paths for each tower.
Finally stopping at last TM.
But the path ahead sets without me setting it
What I am having to do is Auto drive to that TM
Then cancel the Path AI has set.
Is there a way of stopping it setting

Hope this makes sense

Matt

Think I have solved it
have set that path to ASSINGNMENT automatic (Player only).
Seems to work
:hehe:

You could also use EITPathTrigger(think that is the name, not at computer). Path will not be set until trigger reached.
Cheers
