Update to the Module/Table construction plan. Module-5 rolls-out in the direction indicated by the arrows, which matches the alignment direction of the double-mains departing the tunnel at the bottom. At the right end of Module-5 the track alignment does not match the direction of module roll, so a slide in track connection won't work. Instead, there are three section track pieces that will drop in, with rail joiners that slide into the section, to allow lift out, and the replacement and joiner slide. This will have a tie at each end separate from the track section, and beneath the joiners, embedded in the ballast and not moving with the track section.
The slide in joint to the shelf section along the mountain can be hidden by scenery and trees. The straight joint on the right side of Module-5 will be obvious, but Oh-Well 
.
