I'm trying to set up a "base" session for the legacy of the BN, so I can just plop a consist down and drive the line without it being a ghost line. However I cant get the AI's to cooperate. they keep having cornfield meets with each other and me at the signals in-between the passing sidings. I don't want to pack the line but it would be nice to have a few roaming around. is there some combination of AI rules that will do this? or a new rule?
