Southern Pacific Switching Layout

[FCIN]

I think the first step in "Planning" my layout should be to find a theme, I know I am going to build an ISL but I can't find a specific theme. Any ideas?

Justin;
You might check out some of the Progressive Rail (PGR) operations for ideas. http://www.progressiverail.com/where_we_go.html. Many of the branch lines they operate serve industrial parks. Seems like several modelers are trying to come up with layouts based on their Lakeville, MN industrial park area http://www.bing.com/maps/?v=2&cp=rf51s77...orm=LMLTCC. There was one such layout in an issue or MR not too long ago.

PGR has a nice simple MNS blue paint scheme and decals are available too http://mgdecals.com/L-234.htm. Could always freelance something and use PGR as your road. Just one of many possible ideas.
