ok... The facts:- N-trak Standard "Modified" Open Frame 2'X4' Straight Module "Modified" to allow for a viewable area under the Mainlines Mainlines go straight across the module The idea:- A future city (a'la- Star Wars, Judge Dredd, etc.) with the mainlines being a "museum" where the trains are a "hologram." Walking areas to either side of the mainlines. The "museum" is to be on the 150th, or higher, top floors. Two "floors" below is the "skyway;" a high speed rail system WAY above the ground. The "buildings" in the background start just below the mainlines by 2" to 3" to give a fill that they are complete. The problem:- Should the background buildings be Z scale for forced perspective? How should the buildings be arranged to give a HUGE city feel? Should I use a form of the Modular sections as mentioned in the Jan/Feb 2003 N-Scale (Pgs. 30-32)? Hmmm.... That's all I can think of now. Looked at all the books and articles on planning and perspective. Need an outside look, I'm standing too close. Your help please, and Thanks.
