For the APA box layout I want the track to be buried in sand, with just the rails visible.
To build up the ground level I painted PVA (white glue) between the sleepers (ties) and filled the gaps with Polyfilla (Spackle).
Tools of choice here are a modified lolly stick to smooth the Polyfilla and a Swiss Army Knife to remove any excess filler from the inside of the rails.
Finally I weathered the sleepers, added a rust colour to the rails and painted the infill a light brown.
This is nerve-racking stuff. I’ve just brought some brand new points (switches) that operate perfectly and I’m spreading glue, filler and paint all around them !
Luckily I seem to have got away with it – the points still work.
I’m not sure about that brown colour though. Something more ‘sandy’ is needed.
