I have been building this layout for about a year now. one thing I have learned is there is a few things I want that the layout doesn't give me. One being the ability to run 072 engines. and the other is a real nice place to park long passenger trains my yards are short. well I can't do to much about the yard sizes yet thinking of putting in a lower yard below the layout. but for the 072 loops I can hang from the ceiling a simple 084/072 loops. well here is the scarm file if anyone wants to play with it
