Scene Selection What to model and what to leave out?

Although I am still very early in the planning stages of layout development, it’s hard to figure out where to cut off specific scenes or industries that I want to model. So far my list of industries and/or scenic features are as follows. More may be added as research develops. 

Station List of Seventh Sub

Station List of Eight Sub

 Redmond

Downtown area including T&D Feeds, and the Redmond Depot

 Building Specialties (this was the name in the 1990’s, not sure if the name was the same, or if a different company own the property in the time frame I’m modeling)

Possible frozen food industry (I just learned out this from a fellow modeler of the subdivision http://www.theinsidegateway.com/Woodinville%20Modelling%20the.htm)

Trestle over Sammamish Slough 

Woodinville

Woodinville Wye Complex and Yard

Woodinville Yard. Doubled Ended Sidings on all tracks

 Bellevue Yard and Associated Industries

This is the 1978 list of industries in Bellevue from the BN SPINS (Shipper Perpetual Industrial Numbering System).

K.L. Beverage (site of present Home Depot store near Wilburton)
Adelphi (site of present Best Buy store next to the above Home Depot)
Mutual Materials (Dock)
Mutual Materials (Hopper) (Just S of NE 8th)
Bellevue Paneling (Immediately N of NE 8th)
Sunset Glass (same siding as Bellevue Paneling. The business is still there!)
Interpace ( near where Whole Foods is now)

All the following are at the Bellevue Yard:
Fibres International

Kirkland (Industry List also from BN SPINS)

 Kirkland (Houghton area):
Pneumatic Tube
Seattle Door
Cascade Drywall
Pace Chemical
Old Globe Feed

Kirkland (near downtown):
Kelley Moore paint
Team track (next to existing Kirkland passing track stub)

N. Kirkland (Totem Lake area):
Monotherm Northwest

American Prefinish
Simpson Building Supply

As a side note I’d like to get a hold of a copy of the BN SPINS during the decade to help figure out what industries were being spotted on a regular basis.

Wilburton

Wilburton Trestle

This is a signature element of the subdivision, but it would be a huge model if build in full size.

Other areas to possibly model

North Bend

Kenmore

Maltby

Snohomish

Bothell

Renton
