Still, sometimes you are late for work or school due to subway breakdowns or delays, and in this case, you can get a “delay certificate” from the Seoul Transportation Corporation.
If you access the website of the Seoul Transportation Corporation, you can see the ‘Simple Delay Certificate’ menu on the left.
If you select this, you can see all subway lines 1 to 8 delayed on that day. If you choose the delay time of the train you used, you can print it out right away from anywhere.

However, sometimes the subway was definitely delayed due to train interval adjustment or transfer, but the delay time is not registered on the Seoul Transportation Corporation’s website. In this case, if you visit the nearest station offices of Lines 1 to 8, the staff will issue a certificate through a simple verification process.

If you visit the station office, we will issue a ‘delay certificate’ like the picture above. It’s a little different from the document I checked on the website, right? You can enter your name on the delay certificate issued by the station office and adjust the delay time.
One thing to be aware of is that the station office of lines 1 to 8 can only issue a certificate of train delay for lines 1 to 8. For example, if you visit the station office of Seoul Station line 4 and ask for a certificate of airport railroad delay for Seoul Station, the staff cannot help you.
The Seoul Transportation Corporation will also make more efforts to prevent any inconvenience caused by train delays, and I hope you do not panic when the train is delayed and get the help you need calmly.
