Liked your layout work, Mike. Looking forward to the next one.
As to doing a build that can be easily disassembled, I'm a proponent of sectional construction, not per se for being able to take it down, but for maintenance issues involving major work. A section can be removed and put up on a vertical stand rather than having to lie underneath it or reach over it for several hours. This is in situations where a turnout or track section needs replacing or major service.
