Hi guys,

I have some Lionel PW tunnel portals, but they won't work for my layout.  I need something low profile that can go right up against the drywall.

Do you have any suggestions?  Color print out pasted on cardboard?  Any 3-d printable files out there?  I found one, but it is not what I am looking for.  An 1/8" - 1/4" thick 3-d printed brick portal would be perfect.  Low profile, but still get the texture.

Obviously I can buy them, but I like to diy stuff when I can.

Any help/suggestions appreciated!

Hi TrainManMike,

Since you said you like to DIY, go to the Clever Models website.

  www.clevermodels.net

They offer some outstanding paper models.  Plus, they offer free samples that periodically change.  As a freebie, they recently, posted a single tunnel portal that uses thin foamboard as the backing material.  You could easily modify their design to make it fit your layout.  I've purchased some of their models and I think they look great.

Honestly I am trying to figure out why you would need something that thin. Is this a fake tunnel facing a track and you need clearance? Would you wall it up, because even if you paint the interior black it will reflect some light and be obvious. Or maybe it's a working tunnel and there is something in the way? I don't know if a tunnel portal that thin will ever look convincing.

But that said, what about ripping down a plastic tunnel portal on the table saw, or carefully with a hand saw? Or use thin foam and build it up block by block right on the drywall as others have suggested.

I have holes cut in the drywall and no real mountain built, so I want something flush against the drywall.  I also have a curve going into the drywall with not much room on either side.

I also thought about using an HO or N portal 3-d print design and enlarging it as suggested early on in this thread.

I'm not seeing why you couldn't use a regular tunnel portal on these, Mike? In fact I would push the portals further from the wall so I could add some rocks around it. The only one I see an issue with is the first, and you could cut the opening a bit more to the left and angle the portal.

If you are determined to have a low profile, put the portal on the drywall, trace around it, and then carefully cut out the drywall. Then you can imbed it as deep as you want. Just put some caulk on the edge of the opening and push the portal in to as close to flush as you want.

What's wrong with Scenic Express tunnel portholes?

What about korber tunnel portholes?

How thin do you need them?
