Hi Dave... Yes, the curve by the sawmill was either 8.5" or 9". The other end was 11". I only ran the Porters and gas mech on the layout along with BVM 20' cars and disconnects. It was fun while it lasted. Let me know if you have any other questions.
What did you use for trackwork on the B&W? I can't decide if I want to do something similar or if I want to just do a multilevel roundy rounder. Either way, I'll be going 2x3 or 2x4 to fit into my office.

I like Peco just fine. I take the time to paint the ties and rail and to bury ties in some places. Because the turnouts are manually operated, I prefer to use the Peco spring loaded ones. If a particular curve is long enough, you may need to solder 2 pieces of flex track together. You need to work through small curves slowly and patiently. Many people don't like Peco because the ties are somewhat oversized. I figure that it's On30, it's my railroad, it's my choice. If you are having fun building your railroad, don't pay attention to anyone else.
As I recall, on the little trestles, I attached the track to the cork roadbed via track nails before and after the trestle. After that track was set, I used 3 track track gauges to hold the rail in place on the trestle (ties removed of course) , and then used CA to attach the rail to the deck. Then I weighted the track down with something heavy (forget what exactly) and left it alone for a day or so.
Sounds like you will have trains rolling in a day or so. Do you have any pics to share?
