That's a very nicely put together layout frame. Light yet strong and a lot of care put into the structure as opposed to pieces of 25mm x 50mm bit of softwood stuck together with ply stuck on the top. Obviously a lot of thought gone into the design.
If this one is going to be a lot better than the old one its going to be quite a layout as the modelling in the old one looked pretty good. Reminds me of my youth when I had a layout at home in the cellar that I put together with my Dad. I still miss that layout all these years later.
