Hello Nick, I am really liking your layout project, I had a plan many moons ago based on Bourne End in 4mm that never really came to fruition. I do love the simplicity of the track layout, and the idea of creating scenic atmosphere with the less is more approach.
but I have something mulling again, this time in 7mm utilising the Dapol O gauge 121’s, of which I have 1 or 2 of 🫣 or may be a few more than that !!
I am following with interest
