Train service was interrupted in parts of Seoul after a ladder truck fell onto the tracks on the Gyeongui-Jungang Line, and resumed after some five hours.

The Korea Railroad Corporation(KORAIL) said some of its electric trains stopped running, including those traveling between Gajwa Station and Seoul Station, after the accident along the Gajwa-Sinchon section around 8:20 a.m. Friday.

The accident also disrupted the power supply to the section linking Seoul Station with Haengsin Station in Goyang, Gyeonggi Province, stopping ten other trains, including a Busan-bound high-speed KTX-Cheongryong train scheduled to depart from Haengsin Station at 8:30 a.m.

Authorities succeeded in restoring the accident site to normal, with train service resuming at 1:30 p.m.

Meanwhile, officials at the Seodaemun Police Station said the blood alcohol level of driver of the ladder truck ranged between 0.03 percent and 0.08 percent, high enough for a license suspension.

The unidentified driver apparently told police that he had a bottle of soju Thursday evening and denied that it had anything to do with the accident.
