Train services on the southwestern Jeolla Line resumed after a brief interruption caused by a cargo train derailment at Jeonju Station on Thursday, the state railway operator said.

The accident occurred around 4:30 a.m., when one of the wheels of a moving cargo train derailed, according to the Korea Railroad Corp.

Two KTX trains on the Jeonju-Iksan section of the Jeolla Line were halted, and passengers were provided alternative transportation on two buses, KORAIL said.

Services resumed around 7 a.m., and an investigation is underway into the cause of the accident. (Yonhap)
