No — Seoul Station is not open 24 hours; the building and concourse close overnight, roughly from 1 AM to early morning.
For travelers that means no indoor waiting after midnight, so a late arrival needs a plan that starts outside the doors.
This post covers the closing window, last trains by line, places to wait nearby, airport options after the last Arex train, and what still works while the station is shut.

is seoul station open 24 hours? The short answer: closed around 1 AM
Seoul Station is not open 24 hours — the building and concourse close overnight, roughly from 1 AM to early morning.
The commonly reported figure is around 1 AM for closing and around 5:00–5:30 AM for reopening, timed so the doors are back open before the first Arex trains.
Per the published line schedules, the last trains from Seoul Station — Line 1, Line 4, Gyeongui-Jungang and Arex — all leave between roughly 23:30 and 00:30 depending on line and direction.
After that window, the only ways out are wheels and roads: taxis, buses or a bike share.
The exact closing minute is a commonly reported figure rather than a number confirmed on an official Korail page, so check the official timetable for the line you need instead of planning around 1:00 exactly.
The closure only affects two kinds of travelers: those who miss the last train and those arriving before 5 AM.
If your train gets in after midnight, heading straight to the taxi stand or a 24-hour convenience store outside the exits beats circling a closed concourse.
If the wait is long, Hongdae or Dongdaemun is a 10–20 minute taxi ride with food that is actually open.
| ~23:30 – 00:30 | Last trains leave (Line 1, Line 4, Gyeongui-Jungang, Arex) — exact minute differs by line and direction |
|---|---|
| ~1:00 AM | Station building and concourse close for the night |
| ~5:00 – 5:30 AM | Station reopens; first Arex trains depart |
What time is the last train from Seoul Station?
The last trains from Seoul Station all fall between roughly 23:30 and 00:30, with KTX generally stopping before 23:00 depending on the destination.
Line 1, Line 4, the Gyeongui-Jungang Line and Arex each publish their own final departure, and the minute changes with direction.
| Line | Last departure from Seoul Station |
|---|---|
| Line 1 | ends between roughly 23:30 and 00:30, varies by direction |
| Line 4 | ends between roughly 23:30 and 00:30, varies by direction |
| Gyeongui-Jungang Line | ends between roughly 23:30 and 00:30, varies by direction |
| Arex (all-stop) | last train around midnight, first train ~05:00-05:30 |
| Arex (direct express) | ends earlier, around 22:00-23:00 |
| KTX | last departures generally before ~23:00 depending on destination |
Official timetable data covers all Seoul subway Lines 1–9 at 405 stations, published per station, so the exact last-train minute for your line is a lookup you can do before the trip.
The same applies to KTX on the Let’s Korail site and to Arex on the Airport Railroad timetable.
The Arex express train to the airport ends earlier than the all-stop train, so a direct-train schedule will not save you late at night.
The first thing I check before any late arrival is the official timetable for my exact line and direction, because last-train minutes differ per line.
If your plan depends on the final departure, confirm it on the Korail or Arex timetable the same week you travel.

Where can I wait late at night near Seoul Station?
After the concourse closes, the waiting options are all outside the station.
Nothing inside stays open — ticketing, waiting rooms and most shops are behind closed doors for the night.
| Fallback spot | What it offers late at night |
|---|---|
| 24-hour convenience stores | open near the station exits, outside the closed concourse |
| Seoullo 7017 | outdoor elevated public walkway connected to the station; some sections may close late at night, so check that night |
| Free Seoul WiFi | 7,216 hotspots citywide, including the Seoul Station area |
| Seoul Bike (Ttareungi) | 3,340 stations across the city, including this area |
| Public restrooms | 2,008 of Seoul’s 4,418 restrooms confirmed open 24 hours |
| Taxi stand at the station | designated stand for rides after the last train |
| Hongdae / Dongdaemun | 10–20 minute taxi ride; both districts run late |
If you need food that is actually open, Hongdae or Dongdaemun is a 10–20 minute taxi ride away and both districts run late.
If you are only killing an hour, a convenience store outside the exits plus the free WiFi is the simplest combination.
How do I get to Incheon Airport if I miss the last Arex train?
If the last Arex train is gone, your airport options shrink to a night bus from another hub or a taxi from the Seoul Station stand, which runs roughly 50,000–70,000 KRW to Incheon.
No all-night train leaves from Seoul Station, so rail is not part of the answer after midnight.
| Arex express (direct) | Arex all-stop | Taxi / night bus | |
|---|---|---|---|
| Time to Incheon T1 | ~43 min | ~66 min | ~45–60 min by road |
| Fare (one way) | 11,000 KRW | ~4,750–5,050 KRW | ~50,000–70,000 KRW to the airport |
| Last departure | Ends earlier (~22:00–23:00) | Runs later (~midnight) | Available all night |
The express costs roughly 6,000 KRW more than the all-stop train and saves about 23 minutes, but it also finishes its day earlier — around 22:00–23:00.
So if you land late, the all-stop train or a night bus or taxi is the fallback.
The one thing I do before relying on any of this is check the Arex timetable and fare page for that day, because the final express departure is the number most likely to have shifted.
If your flight lands after the last all-stop train, book the taxi or a late airport bus before you fly rather than deciding on the curb.

What still works when the station is closed?
Even with the doors shut, three things keep working: online booking, the taxi stand, and your own planning tools.
The Let’s Korail website and app take ticket searches and purchases around the clock, so a next-morning KTX seat can be booked from a convenience store bench at 2 AM.
- Book the next-morning KTX or Arex ticket on the Let’s Korail site or app — open 24 hours.
- Use the taxi stand outside the exits for rides after the last train.
- Plan around the lockers — coin lockers and the luggage storage service follow the station’s opening hours, so they are off-limits during the ~1 AM–5 AM closure.
- Use a 24-hour public restroom nearby and verify a 24-hour pharmacy for the night — Seoul has 5,872 pharmacies, but overnight duty pharmacies rotate, so check Naver Map that night.
Korail’s customer center (1544-7788) operates roughly 05:30–24:00, so ticket changes after midnight have to wait for morning or happen in the app.
The tourist information centers — 16 across Seoul, including this hub — keep daytime hours only, so do not count on one after midnight.
If my train gets in after midnight, I’d head straight to the taxi stand rather than linger near the closed doors, because it is the one option at the station that works all night and gets me to a district where food and lodging are actually open.
