Hi, I'm new to model railroading and am helping a friend wire up his train set. I was wondering if I properly phased all the transformers if I could attach one leg from each transformer together as a common ground for the whole system? Then when it comes to insulating the track for blocks can we just insulate the center rail? A common ground would save a lot of extra wire if I could just tap off the outside rail wherever I needed. I have 2 train transformers and 2 constant transformers for lighting and turn-outs (I've already rewired the turnouts so they aren't powered by the track) I'd appreciate any advice you can offer. Thanks!
