Yard operations

[NW Modeling List]

Mark, having built several layouts Bob Lang is correct, do not build wide, 18" is about max depth for HO and good working depth. for both single and doule track operations and allows an occasional siding or two. Shelf layouts with a peninsula using a view block offers a lot of trackage in a relatively compact area. Keep the height at a level comfortable to you. You might consider two levels, easy to do, just a bit of planning. Also get books of layouts and modify one to your taste. AVOID duckunders!. Keep the aisles as wide as possible, 4' minimum, 5 feet or more. Consider staging yards, next room, on on another level, screened, they do not have to be finished as they are utilitarian.
Good luck, Cal Reynolds.

  Mark,

      This won't answer any of your questions but is a comment on your proposed layout design. 

  An around the room layout with widths of three and four feet will make construction and operation difficult unless you have extremely long arms (it will be five feet from the aisle to the room corners) or have one of those rolling lean over ladders.  

  No scale was indicated.  However, in any scale up through "O" twice around with double track can be done with much less width.  

  A three or four foot duck-under will be brutal.

  You may want to consider thinning the widths and adding a peninsula in the middle for a longer mainline run.  

  You can widen areas for your yard while narrowing others to maintain aisle width.
