Seoul Subway Line 3 (dubbedThe Orange Line) of theSeoul Metropolitan Subway is arapid transit service that connectsEunpyeong District to Gangnam and southeastern Seoul. Most trains head further northwest to serveGoyang via theIlsan Line.^[1] In 2021, the Seoul Metro operated section had an annual ridership of 295,930,000 or 810,767 passengers per day.^[2]

In December 2010 the line is recorded as having the second highestWi-Fi data consumption in the Seoul Metropolitan area. It averaged 1.8 times more than the other 14 subway lines fitted with Wi-Fi service zones.^[3]

Construction began in 1980, and the first section of Line 3 opened (Gupabal–Yangjae; Jichuk opened in 1990) after the completion of work in two stages during 1985, along with subwayLine 4. In October 1993, a second extension to the south was opened (Yangjae–Suseo).

In March 1996, theKorailIlsan Line opened and allowed Line 3 trains tothrough operate all the way to the city ofGoyang. There are two depots nearJichuk station andSuseo station, which are for both Korail and Seoul Metro.

A 3-kilometre (1.9 mi) extension opened on February 18, 2010, stretching from Suseo to Garak Market (Line 8) and Ogeum (Line 5).

On December 27, 2014,Wonheung station opened betweenWondang andSamsong stations.

In January 2013, theSeoul Metropolitan Rapid Transit Corporation, published free guidebooks in three languages: English, Japanese and Chinese (simplified and traditional), which features eight tours as well as recommendations for accommodations, restaurants and shopping centers. The tours are designed with different themes for travel along the subway lines, e.g. Korean traditional culture, which goes fromJongno 3-ga station toAnguk station andGyeongbokgung station on this line that showcases antique shops and art galleries ofInsa-dong.^[4]
