Does anyone know if there is a type of command or rule that will make the AI clear the track when ordered to drive to a trackmark? I issue I have is lets say I have a train drop off cars at a siding. The trackmark is near the clearance point and the train stops when the first car hits it leaving the rest of the cars fouling teh turnout. Is there a way to make the train continue to back in until the engine either hits it or clears it completely?
