what tunnel mouths have you used on your layouts?
someone on ebay (or it may be more than one person) makes plaster moulded tunnel mouths and sells them on there... has anyone any good or bad experience of them? they are in various styles, stone, concrete, brick and double or single.
also I noted these ones...
peco - large stone blocks style and plastic
graham farish - only have twin bore and dark brick
javis moulded out of something
metcalf card kits
woodland scenics more american looking ones
didn't really see any that jumped out at me. I would like single bore double track if anyone has any other suggestions...

All tunnel mouths on my layout are Peco stone ones as that was all I could get at the time.
You can just make out a single track one in the background of this grainy photo

It looks well set in its place and is pretty clear to me in the picture there (possibly a bit too clear with that white pointing ;) )
Tunnel portals... yup, I seem to have a few on the layout; these are all Japanese, so probably not what you're looking for, but posting as a reference anyway. Let me know if you need the details of any.

I've just singled the track and gone to the N gauge peco tunnel mouth. I believe it was an OO tunnel mouth being used as a N gauge double tack before. In both cases, I'm not found of the shape of the mouth continuing round for more than 180 degrees, that wasn't a common shape. Thinking about it I suppose I could have removed a bit of the lower levels of the tunnel mouth as Both, I think, are excessive in height.
However I don't have the time to created my own by putting a layers of polyfilla on plasticard and scribing my own. That may be a upgrade project for the distant future..
NPN of this parish recommends cutting Peco portals around to make them more prototypical.
Having carved plaster on a plywood former for a viaduct, I can't say I'm happy with it. Yet another 1970s technique I picked up on, and thought cool back then.
These days, concerns like Woodland Scenics produce varied tunnel mouths, and, although expensive, if I'd had that choice back then, I'd probably select from those. :beers:
Yeah - I prefer a smaller bore than Peco allow so lop about 5mm off the base of the plastic moulding, dependent on the height of the running rails. My underlay is 1½mm rubber
Hi Tim,
I have 2 rail tunnels, and like you, was not sure which to try. I did not want to use cardboard, so got a Peco plastic one, and a Woodland Scenic Plaster one.
This is the Peco plastic one, during and after final landscaping ......

They have completely different characteristics when it comes to painting them. I used enamel on both, but the plaster one needed a technique more like painting rocks and cliffs, as the plaster is very absorbent. The plastic one used the same method for painting buildings with brick courses.
I also "adjusted" the openings, but had to be very careful with the plaster one, as even though it was about 3 times the thickness of the Peco plastic one it was very brittle.
I did break it :-[ but a little bit of glue soon fixed it as it was a clean break :D
Hope this helps,
All best wishes
Kevin

I've always considered the above item to be bridge sides rather than a tunnel portal? To me tunnels should have a round bore for proper load distribution of all the earth and rock above.
Have used the Peco Tunnel mouths, although the single portal on the right I think was a Knightwing one ? Decided to add a bit of decoration above the tunnel mouths just to make them a bit different.

Andy.
This is the peco tunnel mouth, as you can see it swings in at the lower entrance . Ideally i'd like the curved top, but then going to vertical sides

That is the Peco one I used.
I needed straight sides as my clearances are VERY tight :worried:
The plaster one had straight sides, but the Peco one was not too difficult to adapt. I cut the sides straight down where I needed to, and notched a bit of plastic strip to represent the courses, and stuck it on under the curved top.
All best wishes

I prefer to make my own tunnel mouths to fit the topography of my layout better. I mainly use plywood and base them on actual locations (I have 5 in total).

The other three are Redruth Station, Greenaway and Dainton.
I've used the Scalescenes downloadable card kits (RO 14 tunnel portal) with a brick finish, time consuming to build but economical.
Pleased with the results even though they have no textured relief on them.
Ian.
I'll be scratch building because the tunnel portal at the location I am modeling is very distinctive.
thanks for all the pictures and replies
this is a very useful thread for people to refer to in the future as well i think
i have ordered a plaster one of ebay just to see what it's like
if it's a load of rubbish i'll probably get a woodland scenics one or try peco and cut the slides straight as was explained in above posts
you'd think scenecraft or hornby would make some decent tunnel mouth for n gauge! revolution / dapol / dj model or someone else maybe can take up this challenge. i can't see why it wouldn't be a success as all layouts pretty much have to go 'off scene' with a bridge or a tunnel... (or just a hole in the sky...)
i did see a laser cut ply or mdf kit for a tunnel as well but wasn't too keen
anyway i shall see what arrives in the post!
cheers for your replies - railsquid wins the most tunnel mouths in one picture prize...

To add the scalescenes ones have varios radii for the tunnel mouth , basically a template that you can cut to suit your needs. Currently the layout is in hundreds of bits but I have made about a dozen tunnel mouths / bridges using this method. Helps if you need to place it on a curve.
