Davy I do think the switch to G scale is a good idea. G scale is much more hefty and runs better for your larger area layout in all weather. Your O scale is great to watch you build. Your posts here get me inspired to try a go at the outdoor G scale. Where I live in New Hampshire USA though we start getting the heavy snow/ice and wind in December lasting to early April some years, that's the only limitation.
Hi George, the thought of O gauge for the big circuit didn't phase me ,it was mostly down to common sense economics that I changed my mind and went for the current plan. I already had more than ample G track and probably have enough O to complete that too , so all's good. I also have interests in OO/HO and N and even some Z gauge, however I have a lot of overlaps in my collections so a major clear out is on the cards. !!.
