Seoul subway manners: why it feels so crowded, and what locals actually find rude

It’s 8:12 a.m. The doors open. You look into the carriage and see what appears to be a solid wall of winter coats. There is no gap. There is no air. There is, somehow, a man reading a news article on his phone with both elbows tucked in like a sleeping bat.

Then the person behind you steps forward, and so do you, and so does the wall, and the doors close, and you are on. Nobody said a word. Nobody apologized. Your face is about four centimeters from a stranger’s backpack, and the backpack has a little keychain of a cartoon rabbit looking at you with deep sympathy.

Welcome to the Seoul subway at rush hour. Koreans have a word for it: 지옥철 (ji-ok-cheol), a mash-up of 지옥 (hell) and 지하철 (subway). It’s clean, cheap, fast and safe, and at the wrong hour it is genuinely packed. Here’s why, and what Koreans actually consider rude (not always what you’d guess).

The short version: in a rush-hour crush, silent pressing is normal and not rude. What is rude: blocking the doors, boarding before people get off, sitting in the pink pregnancy seat when you’re not pregnant, sitting in the elders’ seats at the ends of the car if you’re young and healthy, loud phone calls or videos without earphones, a backpack on your back in a crowd, and eating anything with a smell. On escalators, the rules are officially “hold the handrail, don’t walk”, and in practice half the country still stands right and walks left.

Just how crowded is it?

Very, on certain lines at certain times. Korea measures train crowding as a percentage: 100% means the carriage holds its rated number of passengers, seats plus standard standing room. Under the national railway safety standards, anything above 190% counts as “serious” (심각), 170 to 190% as “congested”, and 150 to 170% as “caution”.

According to an April 2024 press release from the Ministry of Land, Infrastructure and Transport:

Line	Peak congestion (2024)	Status
Gimpo Goldline (light rail from Gimpo into Seoul)	199%	Serious
Seoul Line 9	184%	Congested
Line 7	157%	Caution
Line 4	150%	Around the limit

The Gimpo Goldline, a light rail carrying a fast-growing suburb into the city, became so famous for its morning crush that Line 9 commuters got jealous of the attention. A 2023 Chosun Ilbo real-estate piece ran the headline “김포골드라인? 우리도 죽겠다” (“Gimpo Goldline? We’re dying too”), calling Line 9 a 지옥철 with sections around 200%. The government’s plan is more trains: Gimpo is meant to get five extra trainsets by the end of 2026, and Line 9 four more by 2027, bringing peaks down towards 150%.

Line 9’s express trains are the classic case: they skip stations, so everyone wants to be on them, so nobody can breathe on them. It’s ppalli-ppalli in physical form.

When to avoid it: roughly 7:30 to 9:00 a.m. and 6:00 to 7:30 p.m. on weekdays, especially on lines heading into business districts. Visitors: go sightseeing at 10 and enjoy a seat.

Pushing vs. being rude: the unwritten line

Here’s what surprises many visitors. In a packed car, Koreans press together without comment, and stepping into a crowd that’s already full is just how you board. Nobody expects “sorry” for a bump caused by physics. (We covered the strangers-close-together, zero-intended-touch rule in our piece on personal space and friends holding hands.)

But there’s a clear difference between pressure and pushing. What gets the side-eye:

Boarding before people get off. You wait at the sides of the door and let the exit flow finish. Charging straight down the middle is the move everyone silently hates.
Planting yourself in the doorway. If you’re standing by the door and the train stops, step out onto the platform for a second to let people off, then step back in. Staying put like a lighthouse is a classic complaint.
Shoving without a word. If you need to get out from deep inside the car, you say something. Which brings us to the two most useful phrases on the subway.

Say / Mean: “내릴게요!” (nae-ril-ge-yo) literally means “I’m going to get off,” and on a packed train it means “Please let me through, my stop is now, I am a person and not a sack of rice.” Pair it with “잠시만요” (jam-si-man-yo, “just a moment”), the all-purpose “excuse me” of Korea. Say either one while moving, not after you’ve already plowed through.

Nobody minds that you squeezed. They mind the silent shoulder-like-a-battering-ram. And if you hear “내려요!” behind you, turn sideways and make yourself thin.

The platform lines: queuing, Korean style

Look down at the platform. Most Seoul stations have markings that show exactly where the doors will open, often with arrows or lines for waiting on either side. At rush hour, people form tidy queues at these spots, sometimes two lines per door, leaving the middle clear for people getting off.

It runs on nunchi: nobody announces it, everyone follows it, and the one person standing squarely in front of the door gets a very specific kind of silence. Join the end of a line, or stand to the side.

The pink seat: 임산부 배려석

Since 2013, Seoul subway cars have had pregnancy seats (임산부 배려석, im-san-bu bae-ryeo-seok): two per car, at the ends of the long middle benches, in pink. According to the Seoul Metropolitan Government, there were 7,334 of them across Lines 1 to 8 alone as of October 2024, and the subway’s own announcements ask passengers to leave them empty so a pregnant woman can always sit.

Here’s the key detail: these seats aren’t legally reserved. Neither the pink seats nor the elders’ seats come with a law that bans other people from using them or punishes them for it. The pink seat is a policy run on goodwill. And goodwill, it turns out, is a great generator of internet arguments.

One camp says always leave it empty, since early pregnancy doesn’t show and nobody should have to ask (the official line). The other says sit until someone needs it, since an empty seat on a 184% train is a waste. The result is a recurring stream of stories: a heavily pregnant passenger asks for the seat and is told “I’m pregnant too”; a woman wearing the pregnancy badge isn’t offered the seat; a non-pregnant passenger gets scolded for sitting there. Seoul Metro received over 7,000 complaints a year about the pink seats from 2021 to 2023, and 6,286 in 2024, per a June 2026 Weekly Seoul report. In a 2025 survey by the Korea Population, Health and Welfare Association, 79.5% of pregnant women had used the seats, but 60.9% said they’d had a bad experience, and over 90% of those said it was because no one gave up the seat.

For visitors, the simplest rule: don’t sit in the pink seat. Ever. It’s the one choice no Korean will judge you for. Pregnant women in Korea often carry a small pink 임산부 badge on their bag; if you see one, offer your seat even if you’re not in a pink seat.

The seats for elders: 노약자석

At each end of the carriage are the priority seats (노약자석, no-yak-ja-seok), for elderly people, people with disabilities, people with injuries, pregnant women and people with small children. Unlike the pink seat, these are set up under the law on mobility for transport-vulnerable people, and the social rule is much older and much firmer.

In practice, many Koreans read the 노약자석 as the grandparents’ seats. A healthy young person sitting there, even on a near-empty train, can draw looks, or a comment. And this is where age and hierarchy shows up on the subway: in a culture where elders get the first spoonful and the best seat at the table, they also get the corner seat on Line 2.

It doesn’t always go smoothly, and comment sections love the generational fights, where the word kkondae does a lot of work. For a visitor, it’s simple: keep the 노약자석 for people who need it, and stand up for an elderly person on a crowded car.

“Free rides at 65”: true

People aged 65 and over in Korea ride the subway free, a policy introduced in 1984 under the Elderly Welfare Act. (Discounts started in 1980 at 50% for over-70s.)

It’s also very much a live debate. Seoul Metro’s losses from free rides rose from 50.4 billion won in 2000 to 383.3 billion won in 2025, according to an August 2026 report. In March 2026, President Lee Jae-myung asked officials to study limiting free rides for seniors at rush hour, which set off the familiar shouting match between “elder hate” and “fiscal reality”. In a Seoul Institute survey of 2,000 residents that August, 77% supported redesigning the system, with ideas such as raising the free-ride age and adding bus support for over-70s. Nothing is settled. For now: grandpa rides free, and he’s earned it.

Phone calls, videos and loud talking

The Seoul subway is noticeably quiet. Many people are on their phones, but with earphones. The loudest thing in the car is often the announcements.

So noise stands out, and Koreans complain about it officially. Seoul Metro logged 8,049 noise complaints in 2022 and 8,729 in 2023, passed 10,000 in 2025, and recorded 7,520 in just the first half of 2026. Speakerphone calls and videos played out loud are the main targets.

There’s no law against a phone call on the train, but Seoul Metro asks for vibrate mode, short quiet calls and earphones. In real life:

Calls: if you must, cup your hand, speak low, keep it short. “지금 지하철이야, 이따 전화할게” (“I’m on the subway, I’ll call you later”) is one of the most common sentences in Korea, said at a whisper.
Videos, games, music: earphones, always.
Talking with friends: fine, at indoor volume.

Backpacks: front, down or up

Seoul Metro has run etiquette campaigns about backpacks for years, including a 2019 video it called 백팩 바로 메기 (“wear your backpack the right way”). The message: in a crowded car, take it off your back. Wear it on your front, hold it down by your legs, or put it on the overhead rack.

On your back, a backpack is invisible to you and very visible to the face behind you. Every turn you make becomes a gentle slap.

Eating and drinking

There isn’t a widely enforced blanket ban on eating on the Seoul subway, but the unwritten rule is strong: don’t eat a meal on the train. A small, smell-free snack or a sip from a closed bottle is usually fine. Gimbap, fried chicken, tteokbokki or anything with a smell will make the whole car share your lunch, and Koreans will notice. Same for an open iced coffee on a crowded train; one sudden brake and someone’s white coat becomes an art project.

Big stations are full of bakeries and convenience stores. Eat there. You’ll survive the 25 minutes.

The escalator saga: stand right, walk left, stand in two, hold on

This one is a genuine Korean policy rollercoaster.

1998: the government promotes one-line standing (한 줄 서기): stand on one side, let people in a hurry walk up the other. It catches on, hard.
2007: citing safety problems and breakdowns from uneven weight, the government reverses course and launches a two-line standing (두 줄 서기) campaign: everyone stands, both sides, no walking.
2015: the two-line campaign never really caught on, and the government officially drops it. The official advice becomes three safety rules: hold the handrail, don’t walk or run, stay inside the yellow lines.
2026: the debate returns. In a Ministry of the Interior and Safety survey of 1,000 adults in seven big cities, published in August, 50.1% said they stand on one side and walk the other, and 49.9% said they stand in two lines. A literal coin toss. After a public forum in late August, the ministry announced on September 23, 2026 that it will no longer push a uniform two-line campaign, sticking with the three safety rules.

So: officially, hold the rail and don’t walk. In reality, many people stand right and some walk left. Stand still, hold the rail, and let walkers pass. If you want to walk, take the stairs, and your thighs will thank you by about the third deep station with an escalator that seems to go on forever.

The music: from 얼씨구야 to 풍년

You’ll notice that some announcements come with a little tune. The transfer announcement on Seoul Metro’s Lines 1 to 8 has its own background music, and for years it was a bright, traditional-sounding piece called 얼씨구야 (eol-ssi-gu-ya), by composer Kim Baek-chan. It was introduced on Lines 1 to 4 in 2009 for “Visit Korea Year”, to introduce Korean traditional music (국악) to locals and visitors, and spread to Lines 5 to 8 by 2012. For a whole generation of commuters, those few bars meant one thing: wake up, you’re about to change lines.

In January 2023, Seoul Metro replaced it with 풍년 (“Bumper Harvest”) by Park Kyung-hoon, a modern take on the folk song 풍년가, picked in a public vote with 26.53% of the vote. Plenty of Koreans can still hum 얼씨구야 on demand. Either way, when a jaunty gugak tune plays and everyone looks up from their phones, it’s transfer time.

What visitors should actually do

Avoid weekday rush hours if you can.
Line up at the door markings, to the side, and let everyone off before you board.
Say “내릴게요” or “잠시만요” when you need to get through. Squeezing is fine, silent shoving isn’t.
Never sit in the pink seat, and keep the 노약자석 at the ends of the car for people who need it.
Stand up for elderly passengers and anyone with a pregnancy badge, a cane or a small child.
Backpack off your back in a crowd.
Earphones for everything, calls short and quiet, no meals.
On escalators, hold the rail and stand, keeping right if people are walking.
Big luggage? Use the elevator, and if you can, travel outside rush hour. A suitcase on a 199% train is a crime against physics.

One last thing: the silence isn’t coldness. It’s a few million tired people giving each other the gift of quiet. And if you give up your seat and get only a nod, that still counted.

The Seoul subway works because millions of people quietly agree on the same small rules, most of them never written down: wait to the side, let people off, leave the pink seat, keep it down, take off the bag. Follow those, and even the 8:12 a.m. wall of coats becomes something you can ride. Just watch out for the cartoon rabbit keychain. It knows what you’ve been through.
