The train is suspected of taking North Korean leader Kim Jong-un to China.
A special train on March 25 from North Korea passed through the border city of Dandong in China, sparking rumors that North Korean leader Kim Jong-un was secretly visiting Beijing.
Trains have long been the preferred means of transportation for North Korean leaders.
Mr. Kim Jong-il likes to go by train because he is afraid of sitting on a plane, according to BBC.

The ships transporting North Korean leaders are armored and have many amenities.
Mr. Kim’s train usually moves at a speed of 60 km/h.
Security measures were stepped up after an explosion in Ryongchon, near the border with China, in 2004, killing about 160 people and injuring 1,300.

Kim Jong-il has used trains several times to travel abroad to China and Russia.
During dinners that lasted up to four hours on the ship, guests and staff sang Russian and Korean songs together, Pulikovsky wrote in his memoir.
However, observers are sometimes mistaken when speculating about the activities of the North Korean leader based on the appearance of ships.
