The website doesn't really seem to answer any of my questions.
The site give specs for building modules so that when allot of people get together, they all can hook them together. That they match up in height, track configuration, wiring, ect. He was giving you some ideas of how to build sections that can be easily moved..Modules are OK, but if you ever went and saw a bunch get together, the scenes don't flow well. Till they get them connected in a workable fashion, you might have the last one going from a farm scene to a shipping dock.
You can take the ideas for the basic benchwork and keep adding (IE: section A-B-C, ect.). I suggest searching track plan books and online to find a plan that fits your area, that you like, and will work for what you want to do...Then build the sections to fit that. Keeping in mind how you'd disassemble it if you ever wanted to move it. When I built my last large layout I made sure I could take it out in sections...and the mountains when turned on side would still fit out the doorways. If a couch goes easy in and out of a room, don't build build a section bigger than a couch. (see what I mean?) Don't build a layout your gonna be bored with just because it fit, make some decisions and try to meet half way. When I build a new house, it will be built around the layout.
I showed my better half a drawing of what I wanted my new house to look like and the train room was drawn 4 times bigger than the whole house.
She has a different opinion.
Getting back to what he was showing you...have fun building sections and detailing them to match and be able to use in a bigger layout so you don't have to scrap them later if you move...some can be spaced out and filled in between later making them HUGE!
