Thanks for all your replies --
How can I run a command control locomotive withjust the PowerHouse 180W ??
Per the PowerHouse 180W, #6-22983 operators manual on-line,
Figure 1: how to connect the PowerHouse to a PowerMaster,
Figure 2: how to connect the PowerHouse to a TPC unit,
Figure 4: how to connect the PowerHouse to a ZW transformer.
Figure 5: how to connect the PowerHouse to a TMCC Direct Lockon (according to GUNRUNNERJOHN, this setup apparently dis-ables MTH DCS)
I intend to only run the TMCC locomotive & tender, pulling various rolling stock. Per your answers, I do not need the PowerMaster; I would only need that if I wanted to run a post-war conventional locomotive/tender.
This keeps getting more confusing, please help - Thanks again
