Making a grass mound

The ‘flat’ bits of grass were always intended to be a temporary stopgap, this is the original bit by the tunnel:

Goods Yard - Tunnel End

Work started by removing the old ‘grass’:

A template was made of the area from thin card (250g/m²):

A 25mm thick section of insulation board (Kingspan or Celotex) was marked up and glued to the card with Evo-Stik:

The board was roughly trimmed with an old kitchen knife to fit the card, the the top of the mound roughly shaped:

Then smoothed with a surform (this is a messy business!):

The use of the card “base” allows the edges to be smoothed to almost nothing.

Check it fits:

A quick coat of brown(ish) paint to avoid any of the white showing through:

The mound is then covered with a ‘grass’ base. I’ve used Javis ‘‘:

The mound is then stuck to the layout, and finished off with various ‘turf’ scatter, which helps to blend the edges of the mound into the layout.
