Andre,
Good luck with the change. I too don't have 30 yrs of accumulation but AM and SHS made the core units I need or want, minus the GP40. I found if I down sized my layout scheme that what was available worked and could fill my needs. Since you might wonder what I chose, WP is my answer. One GP9 or GP35 will work for my road switcher/roustabout train. The SW9 fills my yard switching needs. Anyway I will miss your presence here in S land. Like Rusty said the light will be on and the door unlocked. Do get a blog or web page up on your railroad so we can keep up with your progress. ****, why do I feel like I'm writing a condolence letter here. Anyway the HO you have shown was top notch and so will your future layout be top notch.
Greg
