It has been a very long time since I posted anything about n scale micro layouts. I recently did a search on YouTube for n scale micro layouts and came across a series of videos by Peter Waldraff where he builds the tiniest working layout that I have ever seen. It forms a loop with an 1 1/2 inch radius! The layout is less than 1/2 a square foot!
He hasn't posted the final video yet. Below are the first five. Hopefully he will post the final one soon!
