I'm searching for a method to construct large block retaining walls like those used in Western Pennsylvania or Pittsburgh area. What do you suggest?
I'm not in Pittsburgh any more, lived there up until 2018, what you suggest look workable to me. Thanks I'm an HO guy.The Pennsy in Pittsburgh? That's my home town!
Meanwhile, I may have an answer for you. These are O scale. I'm guessing you're modeling HO, since you didn't specify. However, in this case, that would be a good thing! It would make the blocks even larger, like the walls you mention.

I made this "stone wall" with foam core. 1. Peeled off the paper on both sides of the foam, 2. Cut the foam into desired width and length,3. Score vertical and horizontal lines on the foam with a pencil, 4. "Pock mark" the foam by pushing wire brush bristles on to the face of the stone, 5. Paint the wall with dark brown paint, 6. Paint the scored lines with a gray or cement color, 7. Dry brush a light beige paint on the "stones" in the wall creating the "mortar" affect between the stones in the wall. I added the cement columns in this photo by cutting/carving them out of green 3/4 insulation foam from Lowes. The hardest part of this process is getting the scored lines straight on the foam.
