The line branches off the existing Seoul – Busan high-speed line at Osong and runs south to Mokpo.

The sleepers will be produced at factories in Incheon and Cheonan which are operated jointly with Taemyung Industrial. They are being supplied to Sampyo Engineering & Construction, Kuedo Kongyung, and HwaSung-Kuedo.

This is Rail.One's second Rheda 2000 contract in Korea after it supplied more than 390,000 sleepers for the 136km Taegu – Busan Kyungbu high-speed line in 2007.
