[Asia Economy Reporter Park Hyesook] The Seoul Metropolitan Subway Line 7 Seoknam extension line, connecting Bupyeong-gu Office Station in Incheon to Seoknam Station, opened on the 22nd.

The Line 7 Seoknam extension line, which started its first train operation at 5:28 a.m. on the day, is a total length of 4.165 km, running from the existing terminal station Bupyeong-gu Office Station through Sangok Station to Seoknam Station.

Construction began in September 2014 and was completed over 6 years and 9 months with a total project cost of 375.7 billion KRW. Trains operate at 6-minute intervals during peak hours and 12-minute intervals during off-peak hours.

The Seoknam extension line is expected to enhance resident convenience and reduce operating costs through the nation's first free installation agreement of T-money and automated station operation equipment.

With the opening of this line, Incheon Line 1 (Bupyeong-gu Office Station) running north-south and Incheon Line 2 (Seoknam Station) are connected in an H-shaped form, establishing a transfer system between Incheon Lines 1 and 2. As a result, passengers on Incheon Line 2 can transfer at Seoknam Station and reach Seoul Gangnam within an hour.

The opening of the Seoknam extension line will accelerate the construction project of the Line 7 Cheongna extension line.

This project extends 10.74 km from Seoknam Station to the Airport Railroad Cheongna International City Station, with seven stations to be constructed. The project cost is 1.3993 trillion KRW, with construction starting at the end of this year and aiming for opening in the second half of 2027.

Mayor Park Namchun stated at the opening ceremony held at Sangok Station the day before, "Going forward, by linking the Cheongna extension line connecting the Airport Railroad, we will establish a metropolitan railway network encompassing Incheon Urban Railroad, Seoul Metropolitan Subway, and the Airport Railroad, creating an Incheon that is accessible from all directions, where everyone gathers in Incheon and then expands globally."
