Inside Kim Jong Un's Impenetrable North Korean Train: Everything You Need to Know

North Korean leader Kim Jong Un prefers to travel internationally by train, using a luxurious yet battle-ready green train known as the "Moving Fortress." The train, equipped with bulletproof windows, reinforced walls, and attack weapons, offers more flexibility and security compared to an aircraft. It moves at a slow speed of 55 km/h due to its heavy armor and can carry luxury vehicles for ground transport. Kim's father, Kim Jong Il, also used trains for his foreign trips. The train journey from Pyongyang to Vladivostok takes about 20 hours. While Kim has flown on some occasions, his private plane is considered unreliable due to its age.
