Got a bit of work done on the layout today. Laid down more roadbed at Georgetown Junction and laid in the sub roadbed (Homasote) in Bethesda. Did some thinking about track laid flush on the sub roadbed in Bethesda vs. laying it on roadbed. I was originally leaning toward all on the sub roadbed itself but thinking about Bethesda there was a nice track profile on much of it. This will be tricky. I do have some large Homabed panels that would work but I think it may be a waste here. We will see! Going to study some more photos and make a decision. Progress is good!
