Nothing is secured so far, as the rock and the pieces of foam will have to be tied together after some more painting. The track itself still needs to be weathered with 2 light coats using the airbrush, as one can see clearly right now how the hole thing shines. The Brawa telephone signal and the Preiser wooden crate will have to be painted as well, then secured to the board.
The last photo shows a small setup using the Tillig ballast, but at this stage the ties only received one batch of drybrushing and a black wash.
