Hi <br /> <br />I Have question that i wouldlike to get answered. If you have a DCC system and there is a point on my railroad where the polarity changes like in a turnaround or a P shaped end line. Does the polarity have to be reversed or will the engine automatically correct the polarity reverse and continue at same speed and direction.
