Retaining Wall, Buttressed (TT)

A buttressed retaining wall at TT (1:120): 50.0mm long, 33.3mm tall and 3.75mm thick, with three battered buttresses projecting 7.5mm down the back — a 6000×4000mm prototype panel, 450mm thick. Sections butt end to end along a cutting. The wall itself is thick enough to be real at every scale offered here; the coping is the part to be honest about, at 0.63mm proud at TT. Brick courses are not modelled: at TT a 3-inch mortar joint is 0.13mm and there is no point pretending a nozzle will find it — this is a massing block you paint and weather. Prints standing on its bottom edge; the buttresses narrow going up, so nothing overhangs.
