If you are running DCC it is possable to have two reverse loop sections wired in series to one reverse module. This means that if a train runs onto one reverse section both of them will flip polarity. You wouldnt want that on DC.I see 2 reverse sections that you will need to get reverse modules or maybe someone else can chime in with a better idea. If you wanted to get away from this you could always just turn your locos around with the turntable?
