This is my first attempt at a track plan for my freelance Plainville, Pequabuck and New London Railroad.  I am looking for some serious feedback regarding the plan. This an ​HO scale​ double-decked layout connected by a helix (upper right).  The modeled area will represent the entire, fictional shortline with staging connections to represent "the rest of the world".  I apologize for the green on the first rendition, just happened to be the color layer I was on at the time.

This is my fav Model Railroading site.. Hands Down! keep up the good work!

So the plan is to build a helix which may span two rooms: a non load bearing wall will be installed to separate the train room from the rest of the basement; however, to conserve ~10 sq. ft. of space, I've decided that about half the helix will lie within the train room while the other half will cross into the rest of the basement and be finished off (with viewing windows) to "blend in".
