AC has been the standard for over a century and just about every piece of 3 rail equipment works on AC. There are very few 3 rail items that are incompatible with AC (eg. an inconsequential handful of sets form the '70s that are DC operated), but there are many many 3 rail items that are incompatible with DC including anything command control. I would drop the starter DC units (or relegate them to DC only lighting or what have you) and grow up into the AC world as has been the tradition for 3 Rail O Gauge for over a century. Lionel only went with the less capable DC power supplies on the recent starter sets as a cost reduction both in being able to use a cheaper power supply and reduce weight of shipping said power supply.
A second postwar ZW would compliment your existing at much less cost than a ZW-L and just may fit your needs and budget.
