Power Districts - Insulated rails at turnout and more

Hello, All!

I'm new to the group and this is my first time posting. I apologize in advance if I didn't do it properly.  I am in the process of building a layout with two main loops using Legacy command.  I don't plan on running any conventional trains.  I do plan on adding DCS once the WTIUs are available (someday, lol).  I just completed my first loop and started on the second.  I would like each loop to be it's own power district powered by 180 watt bricks.  The brick powering my first loop is connected to a TMCC direct lock-on which is then connected to the track via bus wire with power feeds every 8-10 feet and on each leg of my turnouts.  I have no issues with my first loop but this is where I am stuck.  I started working on my second loop, powered by a 180 wat brick, connected to a TMCC lock-on, etc.  I am attempting to connect my loops (they run parallel) using pairs of Atlas #5 switches.  Based on every online article I can read or watch, I understand that only the center rail needs to be insulted in order to separate my power districts.  However, I am running into an issue when my engine(s) and consist go from one power district (loop) to another.  The engine(s) short out or sputter.  Most online resources include a diagram with multiple power supplies and a TIU.  Because I don't have a TIU yet, I am guessing I am doing something wrong.  Based on my current configuration (2 bricks and 2 TMCC lock-ons) am I correct that only the center rail needs insulated?  Do I need to phase the power bricks in some way (IE run a wire from the common terminal of one TMCC lock-on to the common terminal of the other TMCC lock-on)?  Any help and suggestions will be greatly appreciated! 

Thanks,

Karl
