Distance 25.1 km · standard segment time 33 minutes 30 seconds

For this trip on Line 2, Seoul Metro’s published station-distance data records Seocho Station km between City Hall Station and 25.1. Adding the published times for each segment gives 33 minutes 30 seconds. This is a reference for judging the scale of an in-line trip, not a live journey planner that includes waiting time.

Waiting for a train, crowding, boarding and alighting, walking on the platform, and operating adjustments all add time. On days with an appointment or a last-train connection, leave a margin beyond the segment total.

Published segment entries

The list below follows the source records from Seocho Station toward City Hall Station. Each entry shows the published segment distance and standard running time; the total above is the sum of those segment times.

The source does not describe the next train, headway, platform walking, or a real-time destination. Check the platform display and official notices again before boarding.

How the distance and time are calculated

The Seoul Open Data Plaza file supplied by Seoul Metro includes line number, station name, cumulative distance, distance from the preceding station, and segment running time. This article uses the cumulative-distance difference for distance and adds every published segment time between the selected records.

It is therefore a rail-route distance, not a straight-line or road distance. It is also a standard running-time reference, not a promise of the arrival time if you leave now. Transfers, waiting, fare gates, and exits are outside the calculation.

Why your actual journey can take longer

Waiting for a train, crowding, boarding and alighting, walking on the platform, and operating adjustments all add time. On days with an appointment or a last-train connection, leave a margin beyond the segment total.

Branch services, turn-backs, maintenance, events, and safety checks can also change the practical route. For transfers or the fastest route at the current moment, use a live map and official service information alongside this reference.

Before leaving Seocho Station

Use the following order to turn the published reference into a safer travel plan.

  • At the Seocho Station platform, check the next station and destination that continue toward City Hall Station
  • Add platform walking and train waiting time to the published 33 minutes 30 seconds
  • Allow extra time during commuting peaks or events
  • Near the last train, confirm the actual terminus and transfer availability on the display
  • Add walking time from City Hall Station to the final destination separately

How to read this data carefully

Some source records repeat the same station name at different positions on one line. The connected search page marks these as separate record positions, so confirm the line, direction, and selected record rather than relying on the name alone.

Distances use the source’s one-decimal cumulative figures, and times are the sum of its minute-and-second entries. Treat the result as a planning reference for number of segments and reasonable time allowance, not as a live arrival prediction.

Frequently Asked Questions

Does it really take only 33 minutes 30 seconds from Seocho Station to City Hall Station?

No. 33 minutes 30 seconds is the sum of Seoul Metro’s published segment running times. Add waiting, crowding, stops, and platform walking time.

Is 25.1 km a straight-line distance?

No. It is the rail distance calculated from the cumulative-distance difference on the same line.

Is the reverse direction the same time?

The same segment totals are a useful reference, but waiting, destination, and operating conditions can differ by direction and time.

Can I plan a transfer from this article alone?

No. This article covers published records within one line. Use a live map, station displays, and official Seoul Metro information for transfers.
