I have built a 15' by 6' oval layout that replicates the Frisco route from Wheatland to Amber Oklahoma.  It is 24 miles with 18 industries to serve.  In real life there was not that many but I am using my creative imagination.  It has 8 locomotives and about 100 cars on it.  I try to hold a 2 to 3 hour operations session about once a month.  The setting is around 1973.  The layout is in the latest N-Rail newsletter and I did a presentation on the layout during the October Zoom meeting. I have attached the article I wrote for the newsletter.  If you are in the neighborhood let me know.  I am retired and usually operate it daily on my own.  Happy Friday!
