Officials from South and North Korea on Saturday inked an agreement to set up a joint committee to operate cross-border railways between the two Koreas, a media pool report said.
The 16-point agreement was signed at the end of three-day talks in the North Korean city of Kaesong.
Through the joint committee, experts from the two Koreas will discuss technical matters related to the operation of two inter-Korean railways, which have not yet been restored since the division of Korea in 1948.
They also agreed that the South will help the North design and build four new railway stations and renovate two others near the inter-Korean border. All the six railway stations are located along the two inter-Korean railways.
Following a historic 2000 inter-Korean summit, the two Koreas have been building two sets of roads and railways. One set runs across the western part of their heavily fortified border and the other across the eastern section.
But the construction work has been delayed amid tensions over North Korea's nuclear weapons programme.
The road and railway which run through the western border and link Seoul with the North's north-western city of Sinuiju located near the Chinese border will pass Kaesong City, where a joint industrial park is being built.
The road linking Seoul with Sinuiju will be completed by the end of June and the railway running along this road will also be linked by the end of this year, according to Vice Finance and Economy Minister Kim Kwang-Rim.
Kim headed the South Korean delegation to the inter-Korean economic talks.
A planned road and a railway link in the east is also planned, although a makeshift, unpaved road was opened in the area last year to take South Korean tourists to the North's scenic Mount Kumgang.
