Finally back on this after years. Been doing past/present industry research and getting as many actual photos of this line as I can. Working out some track arrangements and ordering the remaining jigs tonight.
This was going to be a shelf layout but I have moved 3 times in the past decade and will prob move again soon. So I will do 4' x12" modules, with eventual islands for some industries.
Going to model what should be 65 scale feet but will do between 50-60% compression on whatever I can, so 35ish feet of this is the plan/goal.
The line is part of the Union Belt of Detroit , know as Detroit West Belt and sometimes referred to (from my research) as Highland Park Industrial.
10 or 12 years ago bought an 1985 CR ZTS (Toledo Division) to see all the 'older' trackwork in Detroit and get some layout ideas, as soon as I turned to the page in the photo I knew this was the project I wanted to do. Will do early to late CR and current CR Shared assets, might run some 70's PC on it as I will include some industries that failed/moved and are not proto for the eras mentioned.

That radius is just scribbled in *
