Like many of you I've been into trains since I was a boy. But since graduating college, I've never really had an opportunity to build a dream layout. I enjoyed a 20 year career in the USAF. It was an honor to serve, but moving every 3 years is not conducive to building a large layout. I've been a civilian now for 14 years. But work and raising a large family (8 kids) left little time to attempt building a railroad empire, even though I had a basement. Trains around the tree once a year had to suffice.
With the first 6 of our kids now either out of the house or in college, I find I have more time for trains. We now live in TX. No basements here, so my first attempt at a "layout" is little more than a 8ft by 16in portable shelf that I can put up in a closet when not in use. While dimumituve, my little slice of hi-rail heaven has been great fun and a great learning experience. I've laid and ballested Gargraves track and switches, built and kitbashed structures, and operate my trains via DCS. My steam engines chuff and puff up to get coal at the tower, water at the plug, toot whistles at the grade crossing, and pause at a depot for orders on their short 8ft journey, only to do it all over again.
While this little portable layout has provided me hours of fun, I now yearn for more. I'm planning a new layout to be comprised of two 8ft shelves in an L configuration. The key feature will be a roundhouse and turntable. I can't wait to get started.
I'm certain this new adventure will provide more years of fun. But then what? Eventually I will once again yearn for something more. All this to get to the question in the title. Is the desire to expand your layout ever satiated? Does anyone have a layout that has lasted 10 years or more? Maybe there is as much or more fun in the layout build journey rather than operating the "finished" creation. Of course there is no right or wrong answers, but I'd appreciate perspectives from those who may have had more opportunity to build a dream layout
