Boy, almost three weeks since my last update!
I've continued working in the Glenrock siding area, and have finally carved up the first sheet of foam for the area between the track and the fascia.
Here's one end of the Glenrock area with the foam in place but not carved:

And here's the same spot from a different perspective after the rough carving was done:
The flat spots at either end are for additional foam stacks. Before I extend the foreground foam at the fascia, I'm going to paint the backdrop hills and try my hand at building the first section of scenery base behind the Glenrock tracks.

I've left the Glenrock area alone for the past week or so and am focused instead on getting the roundhouse floor and radial tracks installed at Laurel. That will give me a place to store locomotives - they've been parked out on the NP mainline and Laurel yard forever!
