Is this possible? I want trains in my stacker to continue stacking, but trains not already in the stacker to not go to the stacker (based on schedule/circuit condition).

Hi
I am not quite sure what do you mean
Could you please add details?

Sorry I don't check this site very often- What I mean is, I want the train to skip the fulfilled station before it decides to go there.

A -> B -> C

Train at A goes to B if the station is not fulfilled, or else it goes to C
Station B gets filled and now all trains go to C. What I want is trains already on their way to B keep trying to go to B, and trains at A go directly to C

And this mod is not already doing that? I would have thought it only checks the trains schedule when the trains status changes (train leaving station event to be precise).
