Maybe consider a weak magnet let into one side and a flat steel washer on the other. You are just trying to keep from pieces sliding around, right?
Wow, didn't notice gaps from the pic. If you ever get a chance, or have a photo of the layout with the mountain tops removed, I'd love to see it... Maybe some kind of rock ledge or shrubbery(flexible) either below or above gap or is some sort of attachment, magnetic or otherwise is needed to hold in position? Wish I did the mountain top removal like you for my railroad. While have an access panel, your removable mountain tops definitely better!
I'm now thinking a mix of these is my best bet. Being an eastern road, the foliage should be thick and that'll help out too.
I'll have a tunnel at the back of my layout, but the backside will be open, with the exception of some supports for terrain above the tunnel. I may have to put a black drape or removable panel on the back side, just to keep light from showing through at the portals.
Foamwork is complete, and the layout and room are cleaned up. Layout runs well. Next step is to paint the tunnel portals and retaining walls in concrete color. I picked up a headcold in recent travels, so don't have much of a head of steam to break out the airbrush and get to work. Meanwhile, it's fun to just run some trains.
That is looking GREAT sir! I am really enjoying seeing how it is all coming together. The contour on the mountains is cool and bet it will look super when the ground cover starts going on. Do hate to hear about the head cold. Hope that passes quickly.
Looks great, wish I could expand the photo to get a closer look? I think if you make it a thumbnail picture you/we can expand it? At least that's how my thumbnails here work? Hard to get a "Head of Steam" if you have a "Head Cold" Get it? BTW, do the mountain tops remove on both ends for maintenance?
Thank you. The mountains look naked at this point. The colors are there only to cover any hint of white or pink foam. After I get my tunnel portals and retaining walls painted and set in place I'll need to do a deep dive into scenery techniques. There's much I don't know, so I might pick up a book or two and look at some YouTube videos. I recall that you too were not feeling well recently. I hope that you're better.
Wow, that's amazing and I like the ability to produce large volumes of trees there. Thank you for the link. With an eastern road, I'm going to need a bunch of trees.
I have all of my portals, retaining walls and bridge piers airbrushed in concrete color. After everything dries, I'd like to dirty them up a bit. I bought some flat black paint and thinner at the local hobby shop this morning. What technique should use? How would I go about this? I'm thinking well-thinned paint, airbrush set for low paint flow, a higher air pressure and spraying from a distance? My airbrush is a simple single-action Paasche, about 50 years old. I don't want to overdo it.
Ooops, just kidding. I forgot that I also need to build some walls for my Kato piers at the end of bridges, something that looks similar to the Kato piers, probably made of sheet plastic. I don't know what these walls are called, so attached a photo. [Elmore, AL 10/1990] I need to build and concrete paint four pairs of these before I weather anything, so I have lots of time to mull over the weathering.
Abutments? Chooch make rubber sheets of various building materials like concrete, stone etc. for texturing. Shape foam for the basic structure then cut the pieces/veneer from the sheet, glue to the foam and voila!
Fifer Hobby has all kinds of Chooch piers and abutments... https://www.fiferhobby.com/chooch-n-scale-products/ So does Hobbylinc... https://www.hobbylinc.com/chooch If you are looking for something in more of a smooth concrete abutment... https://www.hobbylinc.com/chooch-co...butment-2-n-scale-model-railroad-scenery-9820
I got a good deal on my Chooch Abutments when I bought them. I bought 4 sets. I have 3 bridges... I cut down the last set and they made some nice 'security barriers' at the entrance to 'Lucky Penny Yard'... .
Thanks a bunch for the ideas @mtntrainman and @freddy_fo , a big help. Out of them all, I'm liking Chooch's 9820 Abutments; I might pick up a package and see what I can work.
