I got lost on youtube today, which is usually a good thing! Today I found this indoor/outdoor O scale layout. [video=youtube;iaj3g3CLJFA]https://www.youtube.com/watch?v=iaj3g3CLJFA[/video]
Live catenary.....you wonder where that name comes from....keeps the catsaway. Comes from the French...nary a cat. Critter control is of high importance outdoors..is as theft control. 440VAC might be a good idea.
I've been paying attention to the interaction between the pantographs and the catenary, I think it's live too.
