Seoul City Councilor Lee Kyung-sook's Safety Inspection of Subway Line 4 Congestion

Seoul Metro "Two Additional Trains Added During Rush Hours on Line 4, Replacement of Aging Electric Cars to Proceed Without Delay"

Councilor Lee Kyung-sook is receiving an explanation about safety inspections from a Seoul Metro official inside the driver's cabin of the new Line 4 train.

Lee Kyung-sook, a member of the Seoul Metropolitan Council's Transportation Committee (People Power Party, Dobong 1), visited Changdong Depot on the 27th to conduct a special safety inspection of subway facilities, including new electric trains.

Changdong Depot is located in Nowon-gu, Seoul, and is responsible for maintenance tasks of electric trains operating on Subway Line 4.

This inspection was arranged to discuss measures to alleviate congestion as the extension of the Jinjeop Line has increased congestion on Line 4.

Before the opening of the Jinjeop Line, the congestion rate inside Line 4 trains was around 162%, but it increased to 186% after the Jinjeop Line opened in March last year.

Councilor Lee Kyung-sook and Park Byung-seop, Director of Safety Management at Seoul Metro, boarded the newly maintained Line 4 electric train at Changdong Depot to conduct a pre-delivery safety inspection together.

At the site, Director Park said, "Since congestion on Line 4 is high during commuting hours due to the extension, we plan to actively manage congestion by deploying two additional new electric trains during these times."

In addition to increasing the number of train operations, the corporation plans to steadily replace old electric trains on Line 4 with new ones to improve passenger comfort. Since 2021, 50 new electric train cars have been introduced and are currently in operation on Subway Line 4, with 210 cars currently being delivered. By 2027, an additional 260 cars will be produced and delivered to Changdong Depot.

Director Park said, "Since unexpected errors may occur with new electric trains, more meticulous inspections are required, so we will pay special attention to safety inspections."

The corporation also reported that Changdong Depot is planned to be relocated to the Jinjeop Depot, which is currently under construction, before 2027.

Councilor Lee Kyung-sook stated, "This visit was a good opportunity to reflect the opinions of Dobong-gu residents in overall subway administration by working with Seoul Metro management to address congestion improvements on Subway Line 4 passing through Dobong-gu and inspecting the safety of depot facilities."
