Himself has spent most of this week adding more rock, and resin fake rock, to the sides of Cutting Mawr.
It occurred to me that the picture I posted last time might not have given an impression of just how deep it is, so this time I thought I would pose one of the WHR saloons on the track to give you some perspective.
The bulk of the job is done now.
He's sent me away with a few more selected lumps of slate to mould and copy to finish off the inside wall and then it will be a case of infilling the gaps with rubble and foliage.
The irony is that most of this will be unseen.
Not only is the cutting so deep that you have to peer over the top to see into it but it's also 15 feet away from the front of the layout.
At least you know it's there, though.
