The station field terminal: a rugged laptop with a sixty key board and a cold blue lit screen standing open at a working angle, sitting on the lid of a gunmetal transit case with corner protectors, its cable trailing off to one side. Dimensions 0.63 by 0.44 by 0.50 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. Static geometry; no rig, skeleton, animation, collision or navigation data. Original design: it carries no maker, model or product name, and no markings, lettering or logos. The screen is an emissive surface with no readable content, and nothing on the model opens, closes or reacts.
