My 3 rail layout is 16 1/5 by 9 1/5 and is in my garage at my home in Florida, my brother is into 2 rail O gauge. He came to visit this past weekend and made a video of my layout. He posted it on YouTube so here it is. He is doing a review on the O gauge hobby and comparing 2 and 3 rail views on the hobby. Enjoy and let me know what you think. I still have to close in the mountain and complete the scenery. As you will see my son still goes up on the layout to play from time to time but once the scenery has been done he will have no room to walk up on it.
