The station workhorse: a two track over snow vehicle on a teal hull, with a curved orange plough blade on push arms, a glazed four light cab, a grating rear deck carrying a lashed fuel drum, roof marker lights, mirrors and an exhaust stack. Each cab door is its own node and swings outward on the rear edge of its opening. Dimensions 2.74 by 2.79 by 5.52 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 rubber tracks, the road wheels, the sprockets and the blade are one rigid mesh and do not move: a track belt cannot be driven by a single node transform, so it is left static rather than faked.
