Hello all! I'm attempting to get a running layout built for the first time in about 30 years - I have N scale rolling stock and have settled on a 36x80 hollow core door (small house with limited space). As I don't want to spiral into paralysis by analysis and attempt to create the "perfect" layout (and never get anything built), I'm looking at using the classic MR Carolina Central plan - seems pretty easy yet provides for looping trains and some switching. I'm planning on Kato Unitrack and have created three options: #1 is the classic version. #2 is a double-track main, but with tighter curves. #3 is the classic, but with a curved viaduct that allows me to have a planned river go off gracefully instead of having to make it disappear behind the hill that hides the staging at the top of the layout. Any thoughts on which seems like the best version to go with, both from an operational standpoint AND giving me the best chance of getting something built in the near future would be so greatly appreciated. Thanks and looking forward to hearing thoughts from some experienced operators!
