@gunrunnerjohn posted:Bruce nailed it, you need to decide what limitations you're willing to live with. FWIW, I forgot about the Coors locomotive, it won't go into my main 10-track yard because it hits the ground throws on the switches.
I decided to give more spacing than needed, at least 4.5-5" with some places with more spacing I guess you never know and its better to do it now than later.
I started redoing the yard for more spacing but dont know if thats really necessary in a yard situation. I am using Ross #6 switches.
