KORAIL president Choi Yeon-hye is appropriately on her way to North Korea by train.
Choi left for Pyongyang on a train from Beijing on Monday afternoon to attend a meeting of the Organisation for Co-Operation between Railways (OSJD), KORAIL said Monday.
The OSJD is an organization of 27 former and current communist countries, including Russia, China and North Korea.
The government approved Choi's request to visit to the North on Sunday after the North sent her a letter of invitation. She got a visa from the North Korean Embassy in Beijing the same day.
The train runs from Beijing to the North Korean border city of Sinuiju in 24 hours, where she switches trains for the 225 km stretch to Pyongyang.
A KORAIL executive said, "Choi's visit is the North's first approval of a South Korean official's visit" since the South imposed sanctions against North Korea in 2010.
She is the first senior South Korean figure to visit Pyongyang since the inter-Korean summit in 2007.
President Park Geun-hye is keen to connect South Korea to Eurasia by railway, which requires cooperation from the OSJD.
