The Grass is Gaugemaster (Noch) spring grass mixed 50/50 with a darker meadow grass. Putting a layer of neat PVA glue on the area required for grassing and then using the static applicator made earlier (from a fly swat), gentle shaking and the grass stands up on end, giving a natural look to the grass. You can see it here applied to the backfill behind the platform and station building. excess was gently blown, hoovered and brushed away.
Trees and Bushes:
The trees were made using previously gathered dead natural sedum autumn joy, cut to size and coloured with added flock covering. The bushes were from Woodland Scenics applied with a bit of glue to the platform diamond fencing. The fencing can be seen in parts when looking from the front.
Here's a picture from around 1910 showing the overgrown foliage we based the atmosphere of our scene from. Our model is based around 1916, so the trees have grown considerably compared to the photo.
