My mind is going a million miles a minute trying to solve all the swing out issues I would have on my layout with something that big. It just won't work on my layout but I absolutely love the idea and the work you are doing. I am a bigger plane brain then train brain and I fly 737s for work so, not being able to model this train is killing me!!!!!!!
FAA is most of the way done with the recertification on the 737 MAX. Spirit Aero and Boeing have started up the assembly lines anticipation of the new certificate approval. Sooooo, soon you'll be able to see these rolling towards Seattle again.
