A 12 m left hand turnout on the 6 m grid: the through route runs straight from rail-a to rail-b, and the diverging route leaves on a 60 m radius to the rail-c port 1.21 m to the left. Concrete bearers grow from 2.5 m to 4.5 m toward the crossing, planed switch blades taper into the stock rails, a crossing casting and check rails sit at the vee, and a clamp lock point machine with drive rodding stands beside the toe. Ballast base at y=0, concrete sleeper tops at y=0.41 and railhead top at y=0.60; 1,435 mm gauge with rail centres at x = +/- 0.7525. The module origin sits on the rail-a port at the track centreline and the module runs toward +Z on the 6 m grid. Bounding size 5.92 x 1.02 x 12.44 m (X x Y x Z). Metre units, +Y up, +Z forward, resting at y=0. Static geometry; no rig, collision or navigation data.
