South Korea: KTX Bullet Trains
Korea has an extensive system of speed bullet trains, known as KTX, launched in 2004. The trains are sleek (more or less), and fast (more or less) at 305 kmh (190 mph). These are not as cool and fast as Japanese Shinkansen but beats American and German junk anytime. Reliable and timely, KTX take you from Seoul to Busan in just a few hours, effectively crossing the entire country diagonally.
