I'm divided over the divider. Sn2Modeler (don't know his real name) made a great point that maybe it is more trouble than it is worth. In retro, he very well could be right! I've been thinking about it for a week or more now.
The divider's purpose was to separate the two sides of the run from each other making the Engineer feel that the layout is really larger than it is. My thought would be that it would be no higher than 68" (the height of my eyes) so that I can see over it and it doesn't interfere with the air circulation in the room. This is very similar to Glue Bob's Ontario Northland layout. Scenic divider not people divider.
The big problem is moving it. If and when I do relocate the layout, the divider has to come down. Also, there are some large knitting mills on this layout (two of them) and the backdrop would separate them from the other side.
An idea...a partial backdrop. Both blobs get a backdrop that taper off to the layout. I like it! Let's give it a try! I can always remove or add the whole backdrop later!
1. Backdrops don't have to cover the whole layout. They can be used sporadically to block scenes.
2. When in doubt of what to draw, pick the one of the options that you think you'll most likely wind up with and draw it. You can always change it later, or even during construction.
3. If trackage is running parallel to the fascia, put the divider at an angle to add interest to the appearance of the layout.
