Hello!  I'm new to this board and have a question. I have a section of ez track that has two parallel straight lines with a switch section in between.  Both tracks are powered simultaneously by one transformer.  Is there any way to insulate the switch so that the two lines can be powered by two different transformers, so trains can run down each line independently but still switch over? I do not have DCC, so when the power is on everything runs on both lines.  I hope I've explained the problem correctly. (I'm kinda new at this.)  Any advice would be greatly appreciated.  Please let me know if you need more info.  Thanks!
