@Ken-Oscale Following up on this as well. Getting back into O-Gauge and I am going to plan/build one of your great designs over the next few years with my son. Your 12x8 L and U shape FasTrack layouts you have posted here are both great options and I could see starting the process on a 4x8 and then expanding over time to add the additional pieces and expand the layout, just as you have mentioned about the phasing in your last post. Just wondering if you were able to publish that article, or if not, if you can share your phased approach here. If it's published, then all the more reason for me to become a subscriber. 
Thanks!
