Chuck,
I hear what you're saying. Think of this table as a beachhead (LOL). As the hobby grows and so do the kids there can be expansion. The height works for a toddler to have sufficient height above the table to enjoy the trains and cars without being too far off the ground sense they are prone to injury. I can make the access port a levered assembly. Unfortunately, I'll have to expand as the job permits. There's a good chance I'll have to move the end of the year, so this first layout will be a fast track build (more toy like than model). However, the table is now a permanent structure and the wife has already started making a play area underneath and added a chalkboard facing on one side. This home we are in now will be our permanent residence once I retire and we've got a permanent train table. Eventually, I'd like to expand to an L-Shape.
