I am planning on building a canyon on my layout and was wondering if anyone had some tips or pictures of canyons they’ve made?
These aren’t Canyons but you can see how I built/carved big rock out croppings out of pink (or blue) insulation foam.

for whatever it’s worth…
thanks

The Cochise & Western Model Railroad Club in Sierra Vista, Arizona, has two deep canyons on it. They were made by cutting out the hollow core doors that the layout is built upon, building a box under the cutout area, and then using blocks of styrofoam out of packing crates and plaster to build the scenery inside the box.
You might get some ideas from looking at how this layout was constructed.

Brandon,
I contacted you via e-mail and you asked me how I made my canyon. I thought I would post here so everyone who is interested could check it out.
I’m not sure where to start here, so I will start at the very basic. Forgive me if this is stuff you already know. The first thing I did was to build the basic bench work for the layout which was two L girders about 35” off the deck. I then decided where the canyon was to go and cut a 30” gap in the bench work and the front girder. I had to reinforce the structure to make it solid after the cut. I then had an area about 30” across by 30” deep by about 3 feet high. I then built all the roadbed supports. There are two track levels - the upper level is about 13” higher than the lower one.
After all the track was tested and I built the bridges, the bridges were removed and I put in the screen. I used window screen and a hot glue gun to make the basic shapes of the canyon and the two mountains on either side. I decided that I wanted the canyon to be really deep so I made the mountains about 5.5 feet tall from the floor. The screen was glued to wood supports where necessary. It actually is quite stiff, so I didn’t need a huge amount of support.
I then applied the base coat of plaster. This is a very messy job. Use old clothes and old shoes and make sure you have a space that you can leave really messy for quite some time. Don’t put old plaster down the drain. Use paper towels to clean up wet stuff and let the plaster set on bowls etc and then crack it off to clean them. I used hydrocal plaster. It is a very hard plaster that is quite strong (when taking down the layout, I had trouble cutting it with a sawzall). I don’t recommend other kinds of plaster for this type of scenery because you need to wail on the whole thing when carving the rock
I actually made a 3’ deep river gorge but I guess a canyon could be built similar. I cut mdf board about 6" wider than the river to form the base… Then I cut 6"x2"x2" “bricks” out of 2" styrene insulation sheet, then using pva glue as morter bricklayed the rough gorge shape. Then , using 3 various Woodland scenics rock molds, made about 350+ plaster rocks and using pva glue on the back of the rock castings glued them to the “brick” gorge walls. Then using a medical ear or mouth syringe injected plaster into the gaps between the castings. The whole lot was then stained the appropriate colours and foliage was added as required.
I very easy way to model a canyon is to glue a few sheets of ceiling tile on top of each other. Let it dry. Now cut the shape of a canyon on the side of the ceiling tile. Now if you want more of a canyon effect cover the ceiling tile with a canyon type paint like a brunt umber.
Canyons often used in mountain railroading to gain elevation. Railroad runs down length of canyon near but NOT at bottom- since bottom of canyon has running water. If not always, then when it rains. Rail line may cross creek back and forth to find best grade, sometimes have to double back to avoid climbing too steeply.
Model railroads often model ONE side of a canyon, with the other side in the aisle.
