The fast way round the station: a single track snowmobile on two steering skis, with a teal and orange cowl, a short windscreen, a headlamp, handlebars with grips and levers, a rear rack and a seat pad that lifts on its rear edge to show the stowage well and its kit bag. Dimensions 1.03 by 1.42 by 3.02 m (X by Y by Z). Metre units, +Y up, +Z front; the origin sits on the ground at the footprint centre unless stated otherwise. Wind blown snow, packed track snow, blue glacier ice, dark teal and safety orange station cladding, off white insulated panel, galvanised steel, gunmetal, black polymer, white and grey and teal cold weather cloth, warm window glow and cold blue marker light. Rigid node-transform clips open, close drive the named parts on their own pivots. There is no skinning and no skeleton; every other surface is static. Original invented archetype: it carries no maker, model or product name, and no markings, registrations or lettering. The skis, the spindles and the rubber track are static geometry: they are one rigid mesh with no steering or drive, and only the seat pad moves.
