'3-rail' diagram?

Jerry Silver <jsilver9@...>

Does the attached/modified 2-rail drawing represent DCC wiring for 'O' gage (3-rail)? I'm new to model railroading and have chosen to use 3-rail 'O' as my base platform. I've not been able to find much information (that I can interpret as 3-rail information) on wiring that is specific to 3-rail. I thought 3-rail would be easy because the outside rails are common and the inside rail is signal. Maybe I'm wrong!!
Advice/council appreciated - THANKS!
