The Sinbundang Line was Korea’s first driverless heavy-rail subway, its operator says, and you notice it as soon as you board: there is no driver’s cab, so the front of the train is a window onto the tunnel. Since 2011 it has carried Gangnam office workers home to Bundang and Pangyo at near-express speed, with stations several kilometres apart once it leaves Seoul.

It also has its own fare. A private line with a surcharge for each section, it is also one of the few rides in Seoul on which the Climate Card does not work. For a visitor, it is the quickest way from Gangnam to a forest park, a mountain trailhead and the tech towns south of the city, all within 20 minutes.

The short answer

  • What it connects: Sinsa and Gangnam in Seoul with Pangyo and Bundang in Seongnam, Suji in Yongin and Gwanggyo in Suwon, on one line of 16 stations.
  • Best first-time stops: Gangnam (Exits 10–11) for Gangnam-daero, Yangjae Citizen's Forest (Exit 1 or 5) for Maeheon Citizens' Forest, and Jeongja (Exit 5) for its café street.
  • The stop most people miss: Cheonggyesan Entrance, the last Seoul station: Exit 2 is about 10 minutes from the Wonteogol trailhead.
  • End to end: 43 minutes from Sinsa to Gwanggyo. The Seoul section ends seven minutes south of Gangnam.
  • The catch: a surcharge of 700 to 2,200 won on top of the normal fare, and no Climate Card.

Where does the Sinbundang Line go?

From Sinsa, just south of the Han River, to Gwanggyo in Suwon, in one red line with no branches. Only the first seven stations, Sinsa to Cheonggyesan Entrance, are in Seoul; Seoul city puts that section at 8.3 km. The other nine are in Gyeonggi-do.

Three owners, one train, two extensions still to come

  • Who runs it: each phase was built by a different private company. Shinbundang Railroad holds Gangnam–Jeongja, Gyeonggi Railroad holds Jeongja–Gwanggyo and New Seoul Railroad holds Sinsa–Gangnam, while Neotrans runs the trains on all three. You never change trains at the boundaries, but the surcharge is charged section by section.
  • Sinsa–Yongsan (planned, not open): according to MTN in June 2025, MOLIT and a Doosan-led consortium began detailed design early that year, with construction targeted for the first half of 2027 and opening for 2032; the planned Dongbinggo station might be dropped because its site, unreturned U.S. military land, is not available.
  • Gwanggyo–Homaesil (under construction, not open): about 9.9 km west to Homaesil with five new stations, including Suwon World Cup Stadium and a Line 1 transfer at Hwaseo. Segye Ilbo, citing the Korea National Railway, reported work 18% complete in March 2026 and an opening target of December 2029.

Which Sinbundang Line stations are worth getting off at?

Seven: four in Seoul from Gangnam to the foot of Cheonggyesan, then Pangyo, Jeongja and Gwanggyo Jungang. Sinsa, the northern end, is the transfer for Garosu-gil, which our Line 3 guide covers; Nonhyeon and Sinnonhyeon are better reached on Lines 7 and 9. Exits below come from the operator’s station pages and Seoul city.

What is there to do at each Sinbundang stop?

North to south, here is why each stop earns its exit, plus one place to eat. Restaurants come from our neighbourhood and city guides wherever one covers the station.

Gangnam (D07) — Gangnam-daero, the part Line 2 skips

Our Line 2 guide skips Gangnam, so this is where the Sinbundang Line earns its place. Its platforms sit four floors under Gangnam-daero, and the operator points visitors to Exits 10 and 11 for the avenue up to the Kyobo Tower crossroads: cinemas, cafés and late-night crowds. Exit 12 is a seven- to eight-minute walk from the free National Library for Children and Young Adults, and Kukkiwon, the world headquarters of taekwondo, is on the same lane, Teheran-ro 7-gil.

For a meal, our Gangnam Station food guide puts Jungdon (Gangnam-daero 110-gil 19-1) first: the byword for tonkatsu in Gangnam, with low-temperature-fried loin and fillet cutlets. Queues form at lunch and dinner, so book a place in line on CatchTable.

Yangjae (D08) — Maljukgeori and an after-work dinner

The crossroads above the station is still called 말죽거리 Maljukgeori, “horse-porridge street”. The operator’s station page gives two stories: travellers stopping at the Joseon-era Yangjae post station fed their horses porridge here, or King Injo drank porridge on horseback here while fleeing the Yi Gwal rebellion in 1624. Today Yangjae is a transfer to Line 3 and, as our Yangjaecheon and Dogok guide puts it, a company-dinner district. Yeongdong Jokbal (main branch, Nambusunhwan-ro 358-gil 8) is the place for 족발 jokbal, braised pig’s trotters, ordered by size with a platter of makguksu buckwheat noodles on the side.

Yangjae Citizen’s Forest (D09) — a forest park with Korea’s modern history in it

Seoul city sends visitors out of Exit 1 or 5 for Maeheon Citizens’ Forest, about 180,000 m² of woods opened in 1986 ahead of the Asian Games and the Olympics. It took its present name in 2022 from Maeheon, the pen name of the independence fighter Yun Bong-gil, whose memorial hall stands inside (free, closed Mondays). Deeper in stand three memorial towers: for Korean Air Flight 858, bombed in 1987, the 1995 Sampoong Department Store collapse and the Yugeok Baengma guerrilla unit of the Korean War. The park hosted the 2026 Seoul International Garden Expo from October 1 to 27.

On the other side of the station, Exit 7 is Seoul city’s exit for the aT Yangjae Flower Market, the country’s main public flower wholesale market, and Exit 5 is also the shortest way down to Yangjaecheon, Korea’s first stream restored by nature-friendly methods in 1995. Our Yangjaecheon guide maps the walk east along the water to the Dogok café street, roughly 40 minutes to an hour, and ends it at Mapojip (Nambusunhwan-ro 2726), a charcoal pork galbi house open since 1993, five minutes from Maebong Station on Line 3.

Cheonggyesan Entrance (D10) — a mountain at the end of the Seoul section

The last Seoul station is a hikers’ station. The operator’s directions are simple: Exit 2, then about 10 minutes on foot to Wonteogol, the main trailhead on Cheonggyesan, a forested mountain on the Seoul–Seongnam border with gentle family routes. Under the expressway bridge on the way in stand a stone Buddha and a three-storey pagoda, Seoul cultural heritage since 1993.

Back down at Wonteogol, Cheonggyesan Gondeure-jip (Cheongnyongmaeul 1-gil 1) serves 곤드레밥 gondeure-bap, rice steamed with dried thistle greens and eaten with soy-seasoning sauce, for 12,000 won, and a grilled bulgogi plate to share. It opens at 10:00 at weekends, ready for the hikers (weekdays from 11:00), with a 15:30–17:30 break, according to a March 2026 listing.

Pangyo (D11) — the tech valley, and lunch in a department store

After Cheonggyesan the line runs its longest gap, more than six minutes under the mountain, and reaches Seongnam. Pangyo is the office town of Kakao, Nexon and NCSoft; its glass campuses are not a sight, but walking between them shows a Korea very different from Gangnam’s towers. The visitor draw is Hyundai Department Store Pangyo, three minutes from Exit 3, and its basement food hall, which our Seongnam guide calls a destination for Seoul shoppers too. With more time, take a bus from Exit 4 to the Pangyo Museum, built over Baekje-era stone tombs (free, closed Mondays); our department store guide explains the food-hall habit.

Jeongja (D12) — terrace cafés by the Tancheon

The operator’s directions from Exit 5: left at the crossroads, right at the Hyundai I-Park towers, and the Jeongja-dong café street is three minutes away. It is a line of terrace cafés and brunch places under the apartment towers along the Tancheon stream, and it works best late in the afternoon and in the evening. Families can take bus 220 from Exit 1 to Korea Job World, a children’s job-experience centre. For lunch before the cafés, our Seongnam guide picks Duhyang (Bulgongnam-ro 5), a large tofu house on the provincial list of Gyeonggi Eumtteum restaurants, known for spicy 순두부 sundubu, soft tofu stew, and naengmyeon. It is in eastern Jeongja-dong, about 1.5 km from the station, so take a taxi or a local bus.

Gwanggyo Jungang (D18) — a lake park in Suwon’s new town

Gwanggyo is a planned new town; the operator says Gwanggyo Lake Park was made from the old Wonchon amusement grounds and Sindae reservoir when the town was built, and that the view of the lakes and towers after dark is the reason to come. Its directions are honest about the distance: bus 52 from the station, about 20 minutes, or a 40-minute walk from Exit 4. For Suwon’s signature dish, take a taxi west to downtown Ingye-dong: our Suwon guide lists Gabojeong, a large marinated-beef 갈비 galbi hall open since 1992 and good for groups. Hwaseong Fortress is in the same guide, with the trains and buses that reach it from Seoul.

And the stops in between?

Between Jeongja and Gwanggyo Jungang the line runs under Bundang and Yongin’s Suji district, mostly apartment towns. Migeum is a second transfer to the Suin-Bundang Line. Dongcheon has an expressway bus transfer stop (Ex-hub) and, seven or eight minutes from Exit 2, the Neutinamu Library, a private library built on one person’s money. From Suji-gu Office, Exit 3 is about 15 minutes on foot from the Suji Ecological Park at the foot of Gwanggyosan. Yongin’s big sights, Everland and the Korean Folk Village, are not on this line; our Yongin guide covers the buses, and Suji’s perilla-oil buckwheat noodles.


How do you ride the Sinbundang Line without paying twice?

Tap in and out with one transit card, and remember that the surcharge is charged when you leave the line. You pay the 1,550-won base fare at the gate, then the operator charges the distance fare and each section’s surcharge when you tap out, or at the transfer gate if you change to another line.

Practical tip

  • No Climate Card. Seoul city excludes the Sinbundang Line from the Climate Card, and the operator says Seoul-only commuter passes cannot board, even at its Seoul stations. A T-money card works; our T-money guide explains transfers.
  • Single-journey tickets cost 100 won more than a transit card and take a 500-won deposit, refunded at the machine when you finish.
  • The Jeongja fare step. From Gangnam, Jeongja costs 2,750 won and Migeum, one stop further, 3,250 won, because you enter the Jeongja–Gwanggyo section and its second surcharge.
  • Cheaper but slower: Line 3 also links Sinsa and Yangjae, and the Suin-Bundang Line, with no surcharge, runs from Seolleung to Jeongja and Migeum. On the Sinbundang Line, Sinsa to Yangjae takes under seven minutes.
  • Sit at the front. With no driver's cab, the first and last cars have a window straight down the tunnel.
  • Short trains. Trains have only six cars; for the busiest times by station, see our crowding ranking and seat etiquette guide.
  • Late nights: service runs until 01:00 on weekdays but only until midnight on weekends and holidays. Check the last train at the station before a late dinner in Gangnam.

What is a good one-day route along the Sinbundang Line?

Start on the mountain, come back through the forest, then ride south for the evening. Avoid Mondays, when the Yun Bong-gil Memorial Hall and the Pangyo Museum are closed.
