O Gauge Wiring

Claude has a wiring question for readers and asks:

“I have about 18 o-22 switches on my carpet layout. I am using a Z transformer with switches on one circut & track on another. My problem is when I turn on the power to the switches the train moves. What is the best way to locate the problem. It was ok before I added the last part of the lay out. I disconected that and others. It didn’t help. I tried several more possible remedies without success. I’m afriad I will have to start from scratch. I think I am missing something but what? Does someone know?”
