Hi Mark,
Thanks for the encouragement on my attempts. My intuition was two loops or none, however I haven't set trains up or made layouts (other than a Christmas oval) The scary part of this project is the sheer lack of knowing what the final product will accomplish. Since I have only seen large layouts on display, the functioning and use/control of a large layout for fun and entertainment is an unknown for me. My other obstacle is imagining different track heights and using tunnels and bridges. I like your layout with the different heights and layers. I am reading as much as I can and hoping to garner some inspiration along the way.
Thanks
John
