Successfully sold my Kato stuff on eBay. I've been picking off some Code 80 Atlas from Fifer. I have my track plan ready for the loco maintenance facility section. It will be 6' x 2' and will tie in with the yard/city section I am planning. I like the simplicity of Kato and it works pretty good, but my layout is going to be a long work in progress and I need to stick with methods that are tried and true for me. Flex track really lets me get the most +19" radius in N scale that I need for my track plan. I still have the Kato Master 2 set for use in running trains while I work on them.
I like having as few rail welds as possible and flex helps there, too.
Atlas may or may not come around with availability, who knows. I have enough to get started. I have the track plan, have refreshed my locos and got the "updates" to my collection. Now I have to clear out the area in the basement, move my office upstairs and start building benchwork. It will take a lot of time as to not shock the "CEO" with a pine empire one evening!
