Korea’s new express train KTX travels at 300 km/hour and this extreme speed calls for extreme design. Every effort has been made to reduce air resistance: Gaps have been minimized, devices under the train have been covered up and there is a sleek texture on the surface of the vehicle.
The biggest challenge, of course, was the head car. But even in cutting edge technology surprisingly simple solutions may be found if engineers are open-minded enough to diverge into another field. In this case it was biology. They realized that nature had done part of the job for them through millions of years of evolution and the front car was modelled after the perfected shape of a shark’s head.
Often nature is used as an inspiration mainly for aesthetic purposes but in this case it was function as well as form.
