Oh Yes,
If it's going to be big, mainline railroading, N scale is the ONLY way to go.
Like I said, that was something I planned, but never really got off the ground...outside of benchwork, & some track...
I am thinking of expanding the K&I by adding a mainline div...nothing quite as ambitious as the CV, but big enough to have some continuous running. This would also have to be N scale.
