Just so folks will know:
The description was written by Ed; revised slightly and edited by me; discussed between Rich, Ed, and me with final revisions added; and approved and posted by Rich.
Again, the intent is to make this designation inclusive of those striving to achieve a high level of realism with their 3-rail equipment, layouts, and operations, without including details that would, in effect, once again make things overly restrictive.
There are many ways to approach realism in the 3-rail world, and each approach has its merits as well as limitations. It's the end result that counts, along with the enjoyment and enrichment individual hobbyists gain in working toward their respective goals.
