一名住在纽约超过10年的Eugene Kim是名Tech Reporter，平日十分依赖纽约地铁系统。
他日前到首尔旅行，发现了当地地铁一些有趣的事物，摘录如下:
（附原文，顺便看看哪些其实我国捷运也有...）

地铁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.

兑钞机
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.

月台层的路线图
The stations are full of big, widely touted subway maps. They helped me find
my way to the right train.

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

列车到站显示器
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.
http://bit.ly/1RBs33n
广告无所不在
There were tons of screens all over the station. Lots of opportunities to
sell ad space.

自动贩卖机（某些月台也有便利店）
Vending machines were pretty common. Some stations had convenience stores on
the platform.

看出哪里不一样了吗？
The train's finally here! See anything strange?

无人驾驶
That's right — no driver! Apparently, it's safer and more cost-efficient to
go driverless.

车内到站显示器
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
讯号稳定的Wi-Fi
And of course, the Wi-Fi connection was solid.
http://bit.ly/1MNr7V7
博爱座
Interesting behavior: Corner seats are left empty, even when the train is
packed, so seniors or pregnant women can find them.

车门开启方向指引
Finally, time to get off. It tells riders which side to exit from.

裸视3D电视广告
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
还是广告
But there was this full-wall screen that ran ads 24/7.
http://bit.ly/1TeHaSK
电动步道
There was also this moving walkway for slow walkers, like me.
http://bit.ly/1MNrIGu
节能电梯
The escalators don't move until someone steps on them. That saves a lot in
energy costs.
http://bit.ly/22I2VA6
干净的厕所
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
贩卖机（含保险套）
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.
http://bit.ly/21Pt9Lq
导盲砖
The yellow line is there to help the visually impaired find directions. It
led all over the station.
http://bit.ly/1WSZ6RD
出口与转乘资讯
I needed this station map to find my way out.

Google Campus Seoul
（位于首尔江南区大峙洞）
https://www.campus.co/seoul/en
Finally found Google's Seoul Campus. That was a fun ride!
