I tested a couple of ideas for detailing around the buffer stops, fuelling point and walling to see what worked and gave me the look I was after. I am after a dated look for the depot so wanted the look of grass and plants growing from the ballast. Once I was happy I continued placing clumps of small static grass randomly around the layout especially the buffer stops and fuelling point. I purchased some Railway Laser Lines yard tower lights to give some height to the scenery, these don't come with any lights but planned to make some on the 3D printer. I started the construction of the refuelling point canopy, made from plasticard and strut with corrugated aluminium sheet for the roof.
