A 6 m level crossing module: rubber crossing panels between and outside the rails level with the railhead, an 11 m asphalt road across the track with edge lines, and a lifting barrier each side of the line on a counterweighted mast, each a named pivot node at its hinge, with a twin aspect warning light head on the mast. 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 11.00 x 2.28 x 6.50 m (X x Y x Z). Metre units, +Y up, +Z forward, resting at y=0. Named pivot nodes: barrier-right, barrier-left. Rigid node-transform clips: open and close. No skinning. No collision or navigation data.
