So once again, I am confused and need help from those that know a lot more than me. When I my had a layout years ago, I used Lionel tubalur track. I used what I believe was the home run or star method of wiring and connected the hot and common to a piece of track within each block. My understanding was that it didn't matter which outside rail was used because they were connected by the metal pieces holding the track together. I am now using Ross/Gargraves track and when I look at it, it doesn't appear to me that two outside rails are connected. So when I wire up the layout for track power, do I have to run common to both outside rails?
