서울메트로 / Seoul Metro

One thing I love about Seoul is the subway system. It's very easy to get anywhere by subway. I'm not from a city, so not having to drive and being able to go a long distance using public transportation is awesome. I've been taking the subway all over the city by myself since arriving here.
While I'm quite fond of the subway, it's not always a good experience. When it's busy you're forced to stand for a long time (if you're traveling by subway for over an hour this can be an unpleasant experience). It's not that enjoyable to be stuffed into a subway car like a sardine. Also, don't be too surprised by people pushing or shoving you. No, they won't apologize either. Maybe it's because Seoul is very densely populated, but people don't apologize when they bump into you, and it's not uncommon for old people to push you aside so they can get into the subway first. Even my Korean friend thinks it's so rude that people shove others aside or bump into them and don't even say anything. This doesn't apply just to the subway.
That aside, I love the subway. It's very convenient.

Since coming to Seoul I've taken a number of photos in the subway. Subway stations and subway cars vary. Some stations look new and are spacious, others are very narrow.
Here are some photos

I've seen these models of Dokdo a few times

If you know you'll be transferring subway lines at some point, these can be very useful! Look for them when you enter the platform. It shows you which cars you should enter depending on which line you want to transfer to and where, so that you won't be far from the exit to the other line when you get off. All subway cars are numbered. You can see the number on the ground or on the outer door. It makes transferring more convenient.

Don't sit at the ends of subway cars. That area is for the elderly. In the following photo, there's an open area instead of seats. It's for wheelchairs, but people with strollers may also use this area, so be aware of that if you're standing there.

see Sistar...

The TVs show you where the next train is and how many minutes it will take to arrive at your station. This information can also be seen on TVs outside the gate, so you know whether you should hurry or not.

TVs on the platform and screens inside the subway cars usually play videos about subway etiquette.

Swipe your card upon exiting and entering the subway area.

There are plenty of signs so it's always clear which station you are at, what the next and previous stations are, and where you need to go to transfer. Navigating this subway system is incredibly easy.

There's also a subway app that is awesome. You can look up exact times and such. It's useful for checking when the last train will come.

The exits are numbered and include a name of a place by the exit (such as a school or prominent building). There are maps of the surrounding area outside the station as well, which point out points of interest.
