Assuming you have an MTH Scaletrax ITAD as shown above. Using the terminology of the Atlas diagram shown earlier, the "PWR" and "COM" connections from the train transformer must be as shown above; this may seem swapped/backwards but this is how to emulate the insulated-rail trigger method using an ITAD.
You would need to jumper the outer rail(COM) terminal to the ITAD COM screw (remove any installed jumper first) to route the common (which is really ground that the Atlas board is looking for to operate).
