I'm a day late and a dollar short (by a year) on this topic and I don't have any expertise (newbie here) to add......but I do want to know:
I have a Railking SW-9 with PS2 that I want to convert to battery power for a backyard layout. If the electronics are removed and replaced with battery and dcc decoder (that has sound), will it run on un-powered track?
Thanks,
MWA
