It's someone else's vision and I have my own for my layout.As you say it probably wouldn't fit your room/shed.If you stripped it down, how much would be usable, since the track would be fixed down, ballasted and probably difficult to remove without damage? Landscaping would probably be damaged at any joins between baseboards. Maybe bridges, tunnel entrances, buildings, signals and other fixtures, vehicles, people, animals could be salvaged? All very good points! I guess this is why second hand layouts don’t appear to be worth that much compared to what has probably been spent on them. But surely there’s a large enough market of people that just want to run trains rather than building themselves?
