I downloaded a demo version of Anyrail, a track-planning program, and after devising several dozen variations of Hemyock I’ve finally come up with a track plan that I’m happy with.
I was determined to include a turntable for operational interest and either a locomotive shed or roundhouse for storing locomotives.
So, without further adieu:
All track components, including the turntable, are Peco Code 80. All turnouts are electrofrog, which should (with a few modifications) keep operations smooth when using DCC. My plan is to operate all locomotives, all turnouts, and the turntable using a single handheld controller.
Big thank you to Tony’s Train Xchange (which, incidentally, is only minutes down the road from my house) who assisted me with ordering all track. Ordering from Tony’s was more convenient than ordering piecemeal elsewhere (and it was considerably cheaper, too).
