Hi Folks,
I found this video on YouTube a few years ago, and just viewed it again. The gentleman is David Hall and I was happy to see he is still active in the hobby. Although he works in HO, his ideas are easily translated into any scale/gauge. These ideas are perfect for those limited on space and funds (no switches/turnouts). His 3rd layout has a very clever design that is rather intriguing. Yes, some custom cuts would probably be necessary in a couple places. Any of these ideas would be perfect in O gauge.
The 3rd layout is at the 6:18 mark, but the whole video is worth the 10 minutes. (I would love to do the 3rd one in O27 tubular or GarGraves flex.) Helps to see trains actually running instead of just an image of a track plan.
Christmas is just around the corner! Time to start now!
Take care, Joe.
