SEOUL, Aug. 9 (Xinhua) -- Officials from South Korea and the Democratic People's Republic of Korea (DPRK) discussed on cooperation Thursday to modernize and eventually connect railways across the border, according to local media.

An unnamed official of Seoul's unification ministry in charge of inter-Korean affairs was quoted as saying that the inter-Korean talks to discuss railway cooperation started from 9:20 a.m. local time.

Six DPRK officials crossed the military demarcation line (MDL), which separates the two Koreas, into the Customs, Immigration and Quarantine (CIQ) in the South Korean side at about 8:30 a.m. local time.

The officials from the two sides were reportedly discussing schedule and ways to conduct a joint on-site survey of the DPRK railways along the western and eastern corridors of the Korean Peninsula.

It was the second of its kind since the first such meeting was held on July 24 at the DPRK's border town of Kaesong.

Railway policymakers of the two Koreas conducted the joint field surveys of the DPRK railway in the eastern coastal area on July 20 and in the western corridor on July 24, respectively.

South Korean President Moon Jae-in and top DPRK leader Kim Jong Un agreed to modernize and connect railways across the inter-Korean border during their first summit meeting on April 27 in the border village of Panmunjom.
