		In order to reduce air resistance, the head part of front and back of the high-speed railroad is designed after streamlined shape of a shark, plus the characteristic of Korean culture which is the soft curve. Bottom of the vehicle where lots of air resistance exist, all devices are covered with coverlets. Even the crevices between cars and small sills of windows and surface of the cars are minimized as possible.
		Existing trains have two trucks (devices that hold up the car) per a car, and on the other hand, high-speed railroad trains have only one truck between passenger cars called articular truck type. This is the most well-known measure from all to reduce the weight of car body.

The source of power that can provide high-speed of 300Km/h is 12 traction electromoters of 1,130kw. When combined with 12 electromoters, 13,560kw, it gives about 18,200 horsepower, which means that this can provide power of 18,200 horses dragging the train.
