200系ときを中心に掲載しています。
EMU Series 200 was designed for the Tohoku and Joetsu Shinkansen lines in 1982. Its design is similar to EMU 0, but the body is made of aluminum and performance is improved. JR East later added cars with a sharp nose and double-decker cars, but the series was gradually withdrawn. By 2010, only renovated trainsets were used for Toki express services.
