Reply to "Lionel 180 Watt Power Brick ... to TIU ?????????????"

I didn't have access to a 3-pole molex, and found that a 4-pole would work.

With its 10-amp capacity, the 180 powerhouse is same wattage/amerage as a postwar ZW, so I use it to drive 2 TIU circuits.  I use a terminal block to make the split.  Be sure to first phase the output with your other transformers; it's a simple matter to switch the output leads if need be when the PH180 is connected to a terminal block.
