I needed to make a long stone wall with a gentle curve in it, rather like your photo. I had a supply of plastic sheets with a stone pattern in them, perhaps Vollmer or Noch or Faller. I created a support for the curve, found a piece of cork roadbed meant for O scale, and glued the sheet of stone pattern to the cork to the curve.
Curious, what about foam? The article in Novembers issue of Model Railroader (page 64-67 by Horst Meier) he discusses using rigid foam to easily cut/carve stone/rock structures. It got me thinking of other uses for rigid foam products, such as retaining walls that you cut/carve to shape and then scribe the block details in. I wonder if florist foam would work (green color found in craft stores in blocks and sheets of various sizes)? Cheap, easy to shape/cut/scribe and very light. Labor intensive? I imagine moreso then ready made retaining walls. But probably cheaper for larger areas. Hey…just throwing that idea out there in the mix. Food for thought.
If you have a considerable area to do and/ or will be needed much more for other areas of the layout, pour a casting from Hydrocal. Build a mold and fit a piece of the sheet packing foam w/ a desirable texture to simulate the cobbling of the block. Use dabs of hot glue to secure the frame/ dams to the base, Pour to about 1/4" once dry remove the frame and peel off the foam. Score the coarse lines as desired. If you are so inclined. you can use one of the castings to pour an RTV rubber mold, this will allow hundreds of castings w/ all those scores to show and save considerable time.

Where is going to be your wall. In relation to the viewer, that is. LION not having any money to buy stuff, usually prints the walls on a color laser printer. Below the stones are too big, and too repetitive, but I could not tell that while making the wall, it only became obvious when I installed the wall.
I used Serif PagePlus X6 to create the wall from a stock bitmap in the program. I could have decreased the size of the stones indefinitely on the computer. I have also created my own bitmaps for use as fills like this.
Him uses a heavyweight 11 x 17 page and affixes it with silicone caulk which will not damage the paper stock. Since it is a laser print it will not run if it gets wet. If you have not a laser printer, the local quick print firm will be happy to do it for you for just a few dollars.
While this abutment looks like it is in the foreground, the whole table at this point is only 16 inches wide, and it really is in a corner, and the road now ramps up past this abutment so that the train will enter a tunnel with the road above it.
I made some bridge piers out of foam and I think they turned out really well. I used an I-beam to make the brick shape and painted and weathered away. The cost was to low to calculate.[tup]
I don’t see why a wall couldn’t be made the same way.
I’m probably late to the game, but here is a wall I made. I bought a rubber mold and poured several wall sections. then cut off the column off one side and installed them in a curve to fit the scene.
Lots of great and creative suggestions here. One product I’ve used that’s economical is JTT Architectural Model Parts #97427 Dressed Stone. Technically, it’s a 1:100 scale item, but works fine in HO, too. At a list price of $6.99, you get two sheets of 7.5"x12" of cut stone, nicely embossed in styrene. Here’s a couple of pics of it I cut and painted, although this scene hasn’t yet really been detailed.
