Editor's Note: Some of this content is going to be submitted to the LDSIG's Journal whenever I get time to finish the article up so don't be surprised to see it again.
I believe the refrain "make only new mistakes" applies to a fair amount of the human condition but let's focus on how it relates to model railroading.
One of the chief complaints about version 1 was the short mainline run.
In trying to fit a super sized adaptation of the original railroad into the new space, I wasn't really fixing that problem, but putting a band aid on it.
I stubbornly continued to try to make it work; even with some serious contortions, the outputs were never good enough to grab me and say "build this!"
It took multiple people, including a LDSig member during a consult at the Indianapolis NMRA convention to tell me to consider a "one way" approach before I finally listened.
I'm glad I did since I ended up getting a design that have 9.5 scale miles of mainline run, generous curves (40" is the mainline standard), the wye at Acca and the Amtrak station at Staples Mill.
