Thanks for the replies. Some of this is fluid, but I plan to have trains that switch out the industries around Grand Junction and West Grove go to the yard. From the yard, they would go west to staging or east to the interchange tracks, Marble Rock or Stockport. I'm highly likely to employ a locomotive in Marble Rock, maybe Stockport. If so, I'll want to add a small spur with an engine shed.
As for reach, I'm 6-2 and can comfortably span 27" to reach a turnout. Of course, said turnouts could be remote operated as well. I've tried to keep all turnouts within 24" reach, and I believe all are within an inch or so. Great point about the Rock! I know there are other railroads I'd like to add that come out of Chicago and come from the west. That said, many of the videos I watch of the C&NW include trains loaded with their rolling stock, and only a few others. With my time frame, I have time to put forth some quality research. I'm looking to develop the history or story of this railway, which I can say has made me much more excited about this build than any other I've developed.
I'm still kicking around the idea of an around-the-wall layout with a lift out and center peninsula. Really, the last thing I want to do is build that type of layout and find that my skill level doesn't permit me to build a quality lift out or lift gate. This is the same reason I haven't considered hidden staging. My lack of patience gets the better of my quality of railroad building on more complex items such as these.
Thanks
Dave
