Hi, I would like to build a huge permanent transparent shinkansen depot, to hold like for 20 - 30 trains on display, all covered from dust as much as possible, as I am sick of taking out and putting my trains back into their bookcases. I do not know how to do it electrically, I mean that the trains there stay while I run a couple of trains, analog, normally on the layout. How could I do this, stationing some while running others ? Do I need at least two powerpacks to handle this ? How do I separate these two "loops" ? And how do I connect them ? How do I insulate the many individual tracks ? Can it work ?Honestly, I have no idea.
