Sadang Station is an important transfer point when traveling between Lines 2 and 4. Unless you check the direction of Line 2, which is a circular line, and the destination of Line 4, you can go in the opposite direction at the same transfer station.
Actual transfer method: Line 2 ↔ Line 4 Sadang Station
Lines 2 and 4 transfer at Sadang Station. Since Line 2 is a circular line, it is important to check the direction of the next station and the remaining stations before arriving at Sadang Station.
When getting off at Sadang Station on Line 2
After getting off at Sadang Station, follow the signs for “Line 4 Transfer” rather than the ticket gate. On the Line 4 platform, the next station and destination are checked depending on whether to go north of the city center like Myeongdong or Seoul Station or toward Gwacheon or Ansan.
- Get off at Sadang Station on Line 2
- Follow the Line 4 transfer signs.
- Check the next station and destination on the Line 4 electronic display board.
- Board the train to your destination
A simple criterion for determining the direction of the city center
When going from Sadang Station to Seoul Station or Myeongdong, make sure it leads toward Isu or Chongshin University entrance. The opposite direction leads towards Namtaeryeong. This information is an auxiliary standard for determining direction, so be sure to give priority to the actual destination on the platform electronic display board on the day.
- Check destination station name
- Check the next station on the platform
- If in the opposite direction, check the transfer aisle sign again before boarding.
Decide before departure
Map your departure and arrival points and see if your transfer to Sadang Station is actually natural. On Line 2, not only the internal and external lines are looked at, but also the next station and the number of remaining stations.
Subway routes vary depending on departure time, size of luggage, and travel speed of companions, even for the same destination. Enter your departure station and exact destination address into the map app, and compare routes with different numbers of transfers and walking sections instead of just looking at the recommended route.
How to read recommended routes
After getting off at Sadang Station, follow the signs for Line 4 and check the next station and destination on the platform. It is a good idea to check the route number on the transfer aisle and the train direction on the platform.
When looking at the sign at the station, check the line color and number first, and after arriving at the platform, be sure to check the next station and destination one more time. Even on the same route, if you take a train in the opposite direction, travel time increases significantly.
Points to save time in the field
Sadang Station can be crowded when commuting and weekend travel overlap. If it's an important appointment, allow extra time if you don't mind missing a train or two.
Especially at large transfer stations, it is quicker to stop briefly and check the signs and map app rather than just following the direction people are moving right after getting off. Instead of looking for directions in front of stairs or escalators, move out of the way and check.
In this case, change the path
If you move only by looking at the color of Line 2, you may make a mistake in direction. Make sure the following station signs match the route in your Maps app:
If there are significant on-site variables such as construction, events, rain, or commute times, the usual shortest route may not be the most convenient route. If the last train is close or an appointment time is important, save alternative transfer stations and taxi pick-up locations in advance.
