Mes Is right you have it wired wrong per the diagram. You probably don't want it to reverse after the wye so put gaps on the end of the wye going into the junction. Put feeders on each of the ends of the turnouts all the same polarity. Have the in of the ar1 get power from the bus. The out part wire it to the line going into the wye. You will also need to gap the rail down that line somewhere preferably before another turnout and long enough for your longest train.
