一名住在紐約超過10年的Eugene Kim是名Tech Reporter，平日十分依賴紐約地鐵系統。
他日前到首爾旅行，發現了當地地鐵一些有趣的事物，摘錄如下:
（附原文，順便看看哪些其實我國捷運也有...）

地鐵APP
The differences are obvious from the beginning of each trip. You don't need
to buy a separate ticket if you download the subway app. It saves a lot of
time.

兌鈔機
But if you want to buy tickets and don't have change, you can use this to get
singles. it saves you from carrying change.

月台層的路線圖
The stations are full of big, widely touted subway maps. They helped me find
my way to the right train.

全高式月台門
This is the platform. These screen doors prevent people from falling onto the
tracks. It saves a lot of people from getting injured.

列車到站顯示器
These screens show where the train is in real time. It gives you an idea of
how much more you need to wait on the platform.

廣告無所不在
There were tons of screens all over the station. Lots of opportunities to
sell ad space.

自動販賣機（某些月台也有便利店）
Vending machines were pretty common. Some stations had convenience stores on
the platform.

看出哪裡不一樣了嗎？
The train's finally here! See anything strange?

無人駕駛
That's right — no driver! Apparently, it's safer and more cost-efficient to
go driverless.

車內到站顯示器
Screens in the subway show the exact time and distance left to get to your
next stop. I was headed to an area called Gangnam to tour the Google Seoul
Campus.

BxxTV??
The shows on the screen kept me entertained ...
http://bit.ly/1RnRfLT
訊號穩定的Wi-Fi
And of course, the Wi-Fi connection was solid.

博愛座
Interesting behavior: Corner seats are left empty, even when the train is
packed, so seniors or pregnant women can find them.

車門開啟方向指引
Finally, time to get off. It tells riders which side to exit from.

裸視3D電視廣告
On my way out of the station, I saw this "3D Holovision" advertising screen.
Unfortunately, it wasn't working when I was passing by.
http://bit.ly/1URAtqK
還是廣告
But there was this full-wall screen that ran ads 24/7.

電動步道
There was also this moving walkway for slow walkers, like me.
http://bit.ly/1MNrIGu
節能電梯
The escalators don't move until someone steps on them. That saves a lot in
energy costs.
http://bit.ly/22I2VA6
乾淨的廁所
I stopped by the bathroom, and surprise! It was really clean! No sketchy
people or trash strewn all over the floor ...
http://bit.ly/1ZGNOSr
販賣機（含保險套）
But this was a little odd. Some bathrooms didn't have toilet paper and sold
them in these vending machines instead. The machine sold things like gum,
Listerine, and ... condoms.

導盲磚
The yellow line is there to help the visually impaired find directions. It
led all over the station.
http://bit.ly/1WSZ6RD
出口與轉乘資訊
I needed this station map to find my way out.

Google Campus Seoul
（位於首爾江南區大峙洞）
https://www.campus.co/seoul/en
Finally found Google's Seoul Campus. That was a fun ride!
