The Annie Part 3 - Design

Fundamentals - how much space is there?
For me, design started with a critical analysis of the available space, balanced against the list of "must-have" items and the style and functionality of the overall layout room. The central stairway leads down to a room on the left hand side of the basement that is 18' long, 25' wide and has a back wall that extends 26' (behind the stairs). There is one center support column in the middle of the room. The walls are painted white, there's top quality carpet installed and there is a full finished ceiling - the layout has to be a furniture-quality accessory to complement the room.

Layout Style: point-to-point 
I decided at the beginning that I would model the Annie as a point-to-point railroad, just as the real line did for over 90 years. However, I also wanted to have a hidden cut-off for continuous running for those times when I just want to watch 'em go 'round.

Design Components and Conventions
There are literally hundreds of ideas that modelers have developed to make their layouts fit their needs. Here are some ideas and how I dealt with them:
Duck-unders:
I think they're a hazard and unrealistic - absolutely not included.
Helix: I think it creates too much hidden running - I want to SEE my trains.
Lift-outs: see "duck-unders" - creates unnecessary hazards, absolutely not included.
Staging Yards: I know some folks love this idea, but I'm just not interested in having multiple trains sitting in a yard waiting their turn to hit the main... plus the Ann Arbor ran two through freights a day, plus locals - so my prototype wasn't overly busy to begin with! 
Double-deck: I strongly considered this, but in the end I decided that I did not want to have scenes stacked, such that I was in the same place for two separate areas of the railroad.
Aisles: If they're not 3' then it's not good enough - there should be room to move without worrying about your elbows.

Preliminary Space Usage Ideas
At first I wanted to preserve space in the room and go with a unique double-deck idea. Then I decided I would get more mainline with peninsulas. But the peninsulas all looked the same, and each scene would be linear. And then I solved all of my problems with the "octopus times two minus one" plan - 15 separate and distinct scenes linking Ann Arbor to Boat Landing! click here to view the 3 space options - this might be a long download, but it's worth the wait!
Developing the Track Plan
Now that the most efficient use of space was determined, it was a simple task for me to design the trackplan. Starting from Ann Arbor I simply sketched each of my must-have scenes in place at appropriate intervals, finishing in Boat Landing. In most scenes I was able to lay out the features exactly as they existed in real life, but you will see that I have used some selective compression in Ann Arbor and Boat Landing and that in the City of Clare I have flipped the unique depot scene so that the cupola of the depot and the crossing faces the viewer... so North is South and South is North, but it makes ME happy... and that's what it's all about. click here to view the trackplan - this might be a long download, but it's worth it!
