The purposes of this diorama are:
1) to get familiar with foamcore and pink extruded styrene
2) to practice and learn how to model water using the the artist medium "liquitex pouring gel'
3) to show my rolling stock in N , HOe
4) to see how my scratchbuilt TT scale metric gauge belgian vicinal rolling stock looks like.

First,some pictures during the building of the diorama

Hi Jacques,
This sounds like a plan to hit more than 2 birds with one stone- Top marks for thinking and multitasking.

I'll be watching how you go with the "water". I have a couple of mountain streams to do soon, and I'll probably need all the help I can get.

I look forward to seeing the diorama develop and the photos along the way.

First , thank you John and Ken for the comments.
Before "pouring" the water here are some details about the diorama:
It measures  30cm x 16cm x 20cm  ( 12" x 7" x 8" )
The track is 9mm gauge  ( Peco  N scale flextrack  )
The diorama accepts  rolling stock of 3 different scales so there is no specific scale element ( like a building for example ) The components are  scale independent : rocks, trees , water etc..
About the culvert:  there are some small and there are some big  culverts  :)
The  different layers:
Base: foamcore
Water: 2 foamcore sheets  5mm  ( 3/16" )
lower embankment: 1 extruded  styrene  sheet  25mm ( 1" )
track
higher embankment : 1 extruded  styrene  sheet  25mm ( 1" ) and sculptamold

All those layers are visible on the picture.

Jacques

The only thing that would give away the diorama scale would be the tie spacing, I guess.

Well,
even Dave Frary and Bob Hayden used standard N track on the Carabasset featured in MR ( when it still was worth reading )

Good point Jose. I should have buried the ties

The stretch of track is short and it is not too late to do it allover again, maybe this way:

Ahh yes, but..
Hi all,
If you bury the ties in ballast/mud there is nothing to give away the sleeper spacing or size.

Remember we are talking narrow-gauge tracks here with Jacques, not finely manicured US Class 1 just-tamped mainline track..

If you use a smaller sized ballast you can just cover your ties and not interfere with your flangeways Have a look at the track to the left of the points in the photo below,

Here I used a thin layer of "HO" cinders over the larger HO ballast to represent a build-up of coaldust/mud between and around the tracks for narrow-gauge O scale,

Most scale ballast is slightly oversize, so if you go down a scale for your ballast, it gives you a finer ballast for the smaller-sized ballast as would have been used under narrow gauge tracks, I'd recommend N-scale ballast to get you up to the top of the sleepers, then "dust up" to cover the top of the sleepers with very-fine cinders sized ballast or coloured tile grout to match your ballast colour. Some of the tops of the larger sized ballast underneath will help add a little more texture to the finer layer on top.

This can be done dry without affecting the rest of the diorama. When you are happy with the look, use an eyedropper and your usual white glue/wet water mix to secure the ballast in place. To minimise the chances of damage to other scenery, always bring your eyedropper with glue in over the trackbed. Any drips will go where they need to go,
