A Victorian steam locomotive constructed entirely from a single uncut sheet of 1869 railway timetable paper through physically impossible origami. The paper's original markings are load-bearing: departure time columns become boiler barrel band geometry, station name typography becomes the tender lettering, route grid lines become the driving wheel spoke pattern. Every mechanical detail — reciprocating piston rods, rotating driving wheels with counterweights, working safety valve on the boiler crown — exists purely as folded geometry, no cuts, no glue, no separate pieces. A single master crease runs unbroken from cowcatcher to tender proving one-sheet construction. A single grain of rice visible beside the cab window for scale. Shot low 3/4 angle, raking side light casting long crease shadows, paper translucent and glowing where folds are thinnest, tatami mat beneath, 8K hyper-detail product photography.
