I am getting back into modele railroading after many years. I went back in using Bachmann EZ track and have had great success with it so far, it made track laying much less frustrating. As I have expanded my small layout I decided to begin to add a small classification yard. I installed three EZ track left hand #4 for the ladder. I insulated each line at the end of the switch to provide independant operation and use an atlas switch box to power each one as needed. The center #4 switch of the three when opened to allow the train to proceed straight into the line works fine, when I close the switch to move the train to the next line the power is killed to the whole line. I suspect I have insulated at the wrong spot but I am lost. Any help would be greatly apprciated!
