Actually one little 'tip' I'm happy to share....
In the earlier days, I found myself having too much fun opening stock boxes and playing trains
So, about two months back, I disconnected all the sections and haven't re-done the wiring yet
The result is that, as it's about 15 minutes work to hook up all the sections and blocks again, the whole thing has been unpowered for 8 weeks, and I actually make progress
That said, I haven't yet laid any new sections, as that would require the wiring live again to verify shorts
I'd highly recommend that if you have work / scenics to crack on with - hide the transformer :)
