I made a 4.5' X 8.5' setup from scratch the layout has two main lines and one secondary a passenger station, a turn table,freightyard, plus more.
What I like about N-scale you can make alot of detail in a small area. I have done modeling since I was 12 years old. But I stopped for a number of years.
I do have more pic's and I am still working on It. I am home only on the weekends.
