OK, here's tonight dumb question from someone who's a neophyte/neanderthal (me) when it comes to hooking things up on a train layout.
I have a Z-Stuff trolley control system. It shows connections to the track power. Got it. It also shows a connection to a 9-12VAC and COM. The COM connection (common, I get it) has two wires coming off it, one to an outside rail, the other to the com port. What kind of 9-12 vac unit do I need? An old transformer? See the attached instructions.
Thanks!
