@ADCX Rob posted:Lionel cataloged DC sets from 1973 to 1991 and multiple thousands were sold. There were several versions of DC power packs / transformers in those sets, including the 4060 that looks like a AC transformer in a black case, but has 4 binding posts(2 DC & 2 DC) and a slide switch for direction.
Yep! That’s the black box I have. Thank you everyone for the input. I feel much better about this now. For a moment I thought I may have done something wrong with the ZW-L.
Tangent question… Is there a way to convert an older engine to AC power?
