I got back to model railroading after retiring around 2006. After a few years, I considered actually building a layout in one of three locations, and played with layout designs with XTrackCad over a year, while reading about DCC, effective track laying, etc. In 2012 construction began and the framing, track installation, wiring, some test setups, control panel, took a good portion of time when not in other pursuits (e.g., golf). The next year I added rough scenery: hills, rocks, etc. Along the way the first years I added structures periodically.
In intervening years the amount of time varied greatly. When I got into building my UP loco fleet I spent lots of time acquiring DC locos and converting to DCC and sound. I like to build most of my freight cars from kits, add flat car loads, etc. And got into adding some simple signals and lighting in structures. Odd projects along the way included setting up a modest vented paint booth and learning to use the airbrush. My time would vary from 10 - 30 hours per week.
In 2020, before COVID, I set out to finally add ballast and complete the scenery by adding ground foam, bushes, etc. That took some concentrated effort, and I added a stream project at one corner. That was the last major effort, so in 2021 I have spent minimal effort. I did take some time to “learn” EBay selling, where I made a pile of items I had bought but never used. It was an un-model railroading project but I wanted to get the learning experience under my belt in case I ever totally downsize.
I prefer creating to operating, having a small run-around layout, so the trains get run more when grandkids visit than otherwise. I’m at a new stage…doing random projects (a new car kit, etc.) occasionally but averaging less than 5 hours per week.
IF we move in upcoming years, I will have the dismantling project, saving just turnouts, signals, structure
