Not sure what I'm looking at here. :confused:It looks like it might be some bit of bricolage.
I think it's using a section of "baked clay" bricks (terre cuite) which are a popular building material here in SW France. They are thermally very efficient compared to "parpangs" cement blocks but very brittle and break easily.
I didn't know that a channel sections were available, sufficiently large to accommodate a G scale train when inverted.
I presume Van did the planning for Daniel's tunnel above:lol:
