Korea's antitrust regulator has approved the merger of state-run rail operators — Korea Railroad Corp.

The approval allows KORAIL to acquire SR's business and a controlling stake previously held by the government, with the integration scheduled to be completed in September. The decision ends a decade-long dual-operator structure under which KORAIL operated KTX services while SR ran the lower-fare SRT network.
