To get the different grains I use strainers and even nylon stockings for the finest grain. The different grains have different colours depending on their origin.

The sand is spread out, covering the sleepers and  a 5-10 millimeters on the outside.
With a brush the sand is leveled leaving the sleepers visiable. 

The sand is moistened with a dropper and water with a little softener. 
This will make it more easy for the diluted PVA glue to cover the hole area.

Then the diluted PVA-glue is applied wwith the same dropper, enough glue to cover all the sand. The dropper should be rinsed with water to stay clean whenever you will take a breake. This takes quite a time and you have to be patient and careful, especially on the wide station areas.  The white PVA glue is diluted with water 50/50 and a few drops of softener.

When the glue is nearly dry it is time to get the sleepers and rails clear of the sand that has stuck there by mistake.

Embankments:
	Here you will have to use the more coarse grains to model stones..

Färg:

When the sand is completely dry the colour has become darker compared to the original colour of the grain.
Sometimes it looks right, but mostly you will have paint the sand to get the right tone.

A light spray with an airbrush to get the red/brown colour of ballast made of stones from the iron ore area.	A light drybrush with white colour gives the ballast a more natural look.
