Just for fun, I scanned some pictures of my first layout, a 3X4' N scale layout that I started nearly 20 years ago!
I call it the Rock Hill and Argyle RR. It was a short line that ran from a connection with the L&N at Argyle, Florida to the community of Rock Hill. The track plan was a simple loop with a passing siding and two spurs from the Atlas book A Clear Track to N-Gauge Fun.
Originally, the layout was on casters and slid under my bed. Later, I was able to put legs on it and make it free standing. It served well for many years and was a test bed for scenery and track laying. Eventually, I moved on to other layouts and sold it to another modeller.
