I got my first train set (Atlas n-scale) when I was in the 4th grade.  Over the past 40 years I've dabbled in the hobby, focusing mostly on track and running the trains.  Never did much scenery.

I find that I now have the time to dive in a bit deeper.  I've switched to DCC and have hand laid a switch that actually works pretty well.  I'm an electrical engineer by training, and I have always like the technical side of model trains.  I hope to also explore the scenery side of things, including both landscape and weathering.
