About
A 6.0 m four-wheel steel hopper wagon: a lofted hopper body with sloping ends falling to a bottom discharge chute, an outside top rail, side stiffeners and a discharge lever. Wheel flanges rest on y=0, so the rail plane sits at y=0.03; place the vehicle at y=0.47 over a matching track module. Coupler ports sit on the buffer faces at y=1.09. Bounding size 2.44 x 2.74 x 6.00 m (X x Y x Z). Metre units, +Y up, +Z forward, resting at y=0. Named pivot nodes: wheel-1-right, wheel-1-left, wheel-2-right, wheel-2-left. Rigid node-transform clips: wheel-roll. No skinning. No collision or navigation data.
