My own view is that people use the term ISL without thinking through what they really mean to do, or even want to do. What sort of prototype activity do you most want to model -- or have you given much thought to that?
----------------------------------------------------
As I stated many times 90% of my layouts been ISLs and I'm still not even close to being a "expert" even though I've been studying these things since the early 70s---that's when I read with MR's Kinnickinnic RY and Dock Company and decided ISLs is my cup of tea since I always like "back alley" railroading.
The main goal of any ISL is of course switching industries and for that goal one must keep in mind what is found on a industrial lead (branch line) and follow that basic principle while designing a ISL.
Of course the urban industrial leads is off the main line or secondary track and twist and turns its way through a industrialized area before it stub ends or in some rare cases loops back to the main line or secondary track..
Another choice is a industrial switching railroad such as the Progressive Rail operation at Airlake Industrial park or some types may serve one large industry-St.Mary's Railroad in Georgia is one example.
Regardless the final goal is switching industries.
