Thanks fellows.
Ron, Welcome. How did you find this thread?
Anyway, you ask some good questions. As pointed out by Toot, you still have some work to do! Remember this thread is about two separate layouts. Since you started at the beginning that is the layout modeling somewhere in the Alaskan Panhandle. The most recent layout is the Southern Division located in Southern Colorado/Northern New Mexico. Let me answer your questions out of order beginning with No. 2. Yes, the first layout was three separate and distinct levels. It was a point to point mining layout. Locos simply went back and forth doing their jobs. Looks like you've spotted the steep incline pictured in Post 48. It was 6.7 degrees! Too steep for realistic operation with HO locos. Some made it on their own, but hauling ore cars was tricky. I got bored with the P to P idea and reworked the layout to have a loop of track for 'running.' The slope was reworked to 4.8 degrees and all my locos, ariticulated locos, had no problems. This was a mining layout. A slope like 4.8 degrees on a layout modeling even West Virginia wouldn't be even close to prototypical and would look plain wrong with any tradition loco, steam or diesel, going up that steep of slope. Try to build using no more than 2.5 degrees if you can.
No. 1. Ground cover. I love doing scenery. Check out the photos on Page 15, posts 144 and 146. Also check my thoughts in post 151. Lastly check out photos on posts 165 and 172. This is what realistic modeling is all about. By reading the posts you will know all my secrets, but the short of it is "when you think you are finished laying scenery, you are not. Do some more." Mother nature layers scenery for thousands of years, we can't do it properly with a couple of shakes of scenery bits. Keep adding and adding.
No. 3. Do overs and replacements. I really didn't ever do anything like I've done in the "redo" category that I've done in this thread. While I had valid reasons to do them I will admit that to keep the thread interesting and have it still be a place for learning I didn't have a mental issue with any redo. Adding trees to this layout's left side was very rewarding to me. Adding the loop of track to the original PCM&T Co. layout was rewarding to me as well. Doing so showed all participants here that these things, redo, can be done, and in some cases should be done.
Hope this helps. As always to everyone keep participating and ask questions. Learning if we can do it is a good thing.
Lastly a side note: I've not been feeling 'right' for sometime now. My back always hurts, but the issue this time is my heart. I go into surgery tomorrow, Wed, for a procedure. If something goes wrong my wife will let you folks know. Best of luck and modeling to you and me. Jim
