My idea is simply this a intelligent modern day dispatch improvement that is capable of detecting a train for example in reality a real train driver wouldn’t get a denied your train appears to be off path message so if we have upto date modern fully working dispatcher it will address those annoying issues by detecting your train and even if having to wait few mins in places for signals to change either a path on current line when no other trains near you or rerouting you if available onto a different line this could easily be considered a leap in technology to me we have TMS technology now so no reason not to fix dispatcher for the better
