Thanks Steve,

             I got it figured out,  Looks like you need to use this config below with a slight tweak.

Just substitute the Tortoise with a Lionel Fastrack Switch

Hook the Black wire to Terminal 2 on the Atlas SICM (Signal Interlock Control Module) and the "GND" on the Switch.  Then the Red wire to Terminal 1 on the Atlas SICM and the "RSC Lights" terminal on the switch.  Finally, make sure JP1 is open on the Atlas SICM.  Works perfect now.  When the Switch is in the Thru Position, the upper Signal shows Green and Lower, Red.  When the switch is thrown to the Diverging path (Out), The Lower signal goes green, and the upper Red.

Oh and you don't need the "Toggle Switch / 12VDC" part of the diagram shown in the first pic. I did use the "Aux In" and "Aux GND" to an AC Power source (Lionel ZW) to power the switch in the test.  Used the same power source for the Atlas boards.
